Realizing that you are pregnant is an emotional moment. You might be excited, nervous, shocked, apprehensive, and everything in between.
It is intense to think of the changes your body will go through, the responsibility you now have for another life and how you will care for your baby.
All of these emotions are heightened because your body is now being flooded with new hormones and more emotional than you might normally be. Pregnant women like to cry when they are watching commercials; it’s normal and even expected.
But with that being said, if you have questions about how far along you are and when you are due you can consult our handy pregnancy week calculator to see where you are currently at with your pregnancy and then you can explore what each week and each trimester has in store for you.
Pregnancy Week Calculator
First, enter the date of your last period (the first day) and the average length, and press the Calculate button to get your estimate as to how far along you are:
When did your last period start?
How long is your cycle?
Here are the results based on the information you provided.
You are:
Time Left:
Your estimated due date is
Please note that this is only an estimation of your due date and conception date
Important Milestones
As stated, the calculator is going to give you the information you need to determine how far along you are. With that, you can determine where you stand in your pregnancy.
Each trimester, which you will learn plenty more about, will last you between twelve and fourteen weeks, and each one will come with its own set of hormonal changes (and body changes), including the different medical tests that you can look forward to.
Another reason for knowing how many weeks pregnant you are will also help you to determine what is normal during each stage and when to worry about certain symptoms.
Another reason is that if you are considering terminating the pregnancy, you will know when the possibility is still there for you to do so.
As a reminder, while we here give you an estimated due date, as does your doctor, the chance of your baby being born on its due date is only 5 percent. There are some though who do have their babies on their due date.
So when you start getting to the end, have your hospital bag packed and ready to go a few weeks early, but also be prepared to go late as well. Whatever the case may be, just be prepared (although you are never truly prepared, especially if this is your first).
What is a pregnancy calculator?
A pregnancy calculator is a way for you to determine how far along you are depending on when your last period was. This requires you to know when the first day of your last period was.
If you don’t then you can always estimate but it might be a little off depending on how close you were to the actual date.
Even when doctors determine how far along you are they use your last period as a determining factor (this is why pregnancies are considered 40 weeks long because the two weeks in between your period and your ovulation period are counted).
This helps you to determine those key milestones when you are pregnant such as when you can anticipate being out of the first trimester (which is what a lot of people wait for when telling others they are pregnant).
How does the pregnancy calculator estimate these data?
It combines two factors; the first date of your last period and the average length of your menstrual cycle to calculate the likely date you conceived. During your cycle, you have a five-day window, your fertile period, as to when you can anticipate getting pregnant.
This is the timeframe in which you ovulate. This happens anywhere from twelve to sixteen days before you have your period.
Now while this is a calculated estimate, based on the exact information that they use when you are at the doctor’s, there are also other signs that you can look out for during your ovulation period to know when you can possibly conceive.
These are to observe changes in your cervical mucus and an increased resting pulse rate.
Some women also report that they have a higher sex drive during that time frame, kind of like the bodies way of telling us this is a good time to get pregnant.
Back to the calculator though, once you input the information, the results will show you your approximate due date and how many weeks of pregnancy you have left.
Let’s look at an example of how the pregnancy week calculator works:
You enter the first day of your last period. Let’s say that date was June 30, 2016. Then you enter an average length of your menstrual cycle of twenty-eight days.
The calculator will project forward and give you a due date of April 6, 2017. On August 10, 2016, the pregnancy calculator will inform you that you are five weeks and six days pregnant and that there are thirty-four weeks left in your pregnancy.
With that information you can begin to plan for your pregnancy.
You will know when your second and third trimesters will begin. These are milestones for women who look forward to that second trimester when the tiredness and sometimes morning sickness dissipates for a period of time, which is always nice.
A pregnancy calculator is a great tool for you to use. We at womanjunction.com know you have questions, which is why we’ve provided you with this convenient tool.
Naturally, you should also be consulting your gynecologist with any questions you have about how far along your pregnancy is and when your due date is.
So while this is something that can give you estimates and knowledge before you get to your doctor, you should still have a professional on your side that can help you with all the medical aspects of your pregnancy.
Remember that this calculator does not replace advice from a specialist. The American College of Obstetricians and Gynecologists state that gestational age is best estimated with the help of ultrasound. The accuracy of ultrasound is high during the first few weeks of pregnancy.
Another important reason to visit your doctor at earliest is to get regular prenatal care. Your doctor will order some blood tests, and imaging tests.
These tests will help you know if you are healthy enough to carry on with pregnancy. These tests may also provide information about fetal health; help exclude certain rare disorders.
Further, a specialist may make dietary recommendations, may advise you about nutrition and supplements.
With that being said, congratulations and hopes for a healthy pregnancy.

Hi, my name is Lebo. My last period was on the 13th January of this year. I was on the depo shot and was supposed to return for a renewal on the 30th December 2017 but never went, If I miss a renewal shot I’m bound to have my period follow a week later. I had sex on the 30th of January and was expecting my period to start again on the 9th of February but they never came instead I experienced cramping for the duration of which I was supposed to be on my period for. We are in March now but I still haven’t had my period. I’m experiencing all the pregnancy symptoms and my stomach is now bloated. When I went to the doctor he did an ultra sound but didn’t find a baby, my blood works were negative but said I have vaginal congestion syndrome but did not say that it’s the reason for my missed periods. Please give me clarity. I have 3 children, one late and the other’s 7 and 4… I know how it goes but when I explain this to the doctor he thinks I’m going insane. Could I be pregnant and still have low HCG levels? Please advise
Hello Lebo, if you are tested after 7 days of a missed period for pregnancy (via a blood test) and it is negative then more than likely you are not pregnant.
Hi, my LMP is Feb 24, 2018, we had contact second week of march and sure dates for March 22 and March 24. We thinking that we had a safe contact because i’m expecting my monthly period on 3rd week of march, but its didn’t. I missed my period. We do pregnancy test April 3 but its Negative and we repeated again April 9, 2018 and the result is Positive . Its possible that i got pregnant on the dates march 22 or 24? or in second week of march? slighlty confusing the first test i done with negative result. when is the best time to take pregnancy test? Thank you
Hello Joy, you are pregnant as you received a positive result on your test.
My last period was on the 1st of February. It was meant to come on the 30th of March but haven’t. I’m 10 days late, I’ve taken 2 test both negative can I be pregnant?
Hello Asti, if you still have not had your period to date then retest for pregnancy.
Hi my last period was the 28/01/2018 which would work out that I am 10 weeks pregnant. I am 100% pregnant btw. But I did have sex on the 2nd December? Could my period in December over the new year and my period in January be false and I am further then I think? Thanks in advance x
Hello Katie, congrats on your pregnancy! The best way to find out how far along you are is through an ultrasound.
Hi my last period was feb.13.18 my period didn’t come at all in March. I was experiencing lower backaches, cramps, cravings, bloated and i was very tired. I took 3 pregnancy tests in March which all came back negative. Then April 2nd came and i started my period. Is there any chance that i could be pregnant or no?
Hi Shenell, if you got your period then I would anticipate you aren’t pregnant. Could have been a myriad of other potential players in your life that could cause the change in your cycle, stress, weight gain, etc.
Hello, my period is usually 32 days..last period started on February 11th.. had sex on February 22 and March 5th.. no period yet& it’s March 30.. took a test on March 27th.. it was negative .. was there a chance I could still be pregnant? Thanks.
Hi Amber, you would have been having sex outside of your fertile period however, if you ovulated early or late you could potentially be pregnant. March 27th May have been too early to test. If you haven’t gotten your period yet I would recommend taking another one. Good luck!
How Many periods can I have while pregnant? I had unprotected sex January 27th and Came On My Period January 28th then came on my period again February 24th this month of March is my only time not having a period, Did I get pregnant in January or February?
Hi Kiera, you most likely would have gotten pregnant at the beginning of March during your ovulation period.
I had sex on February 23 and came on my period February 24 I had a full normal period and took a test March 21st and it said positive and I am about 5 Weeks is that possible?
Hi there Kiera, this could be possible, many times women have what they think is a period while pregnant.
Im phen.. My last menstration is sept. 12 2017.. I dont know the cycle.. I having a twins.. I dont know what weekz of my twins.
Hi Phen, you should have already been to a doctor and your ultrasounds should give you a date, however based on your LMP, you would be about 27 weeks.
Hi,I’m lebo I had my last periods on the 14 February,I had unprotected sex on 3 march.i missed my periods this month
Hi Lebo, have you taken a pregnancy test? If not then I would recommend that and then making an appointment with your doctor.
Hi am 5 weeks late am getting all symptoms did pregnancy test had a very faint line, did it again few days later had no line, what am I supose to do? I know I am pregnant my symptoms are bad…….zars
Hi Zara, if you got a faint line, any line means pregnancy. In general if you no longer get one you either had a false positive on the original test or your HCG levels could be dropping. I would make an appointment with your doctor ASAP.
hi i’m norie i had my last period last febuary 5..my husband just arrived on the 22nd of febuary…until now i don’t have my period..does this mean im pregnant???..by the way my cycle is 35days..thank you in advance..
Hi Norie, you definitely could be. I would recommend a pregnancy test either now or in a few days as today, the 12th would have been your anticipated start date of your period based on a 35 day cycle. And the 22nd of Feb was the beginning of your fertile period as well. Good luck!
i’m 6 days late today, took a PT this morning had a faint line and stayed like that for awhile so i left it out all day came home from work its dark positive line would this be considered a true reading? should i wait another week or so to take another test?
Hello Melissa, once there are two lines, then this indicate the dictation of HCG in your urine which means you are pregnant. You can re-test for pregnancy just to be sure 5 days later using your first urine in the morning. All the best.
I was on prevention pills for a month started on 30/12/2017 until 02 feb 2018 I had my periods on 24jan until 27jan my periods was due on 28feb bt still nothing today I had sex on 03feb and on the 14.15.16 am 41days late could I be pregnant or they are late because of the pills xoxo
Hello Lydia, not sure what these prevention pills are but since you have started to experience this after taking these pills then this might be the reason for the delay in your periods.
