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.

Hey , my last period was October 28th and it lasted 5 days . My husband and i had unprotected sex on November 3rd . Not certain if i was ovulating but my insides definitely felt different . My app says I’m expected to get my period in 2 days and normally I’m spotting by now . I took a pregnancy test today and it came back negative so I’m uncertain if i could possibly be pregnant but the hormones aren’t strong enough or if i should just wait until end of month to take a another test If i don’t get my menstrual ..
Hello Ashley, you should take another test on the first day of your missed period. Tests can give false negatives whet taken too early, and all depends on their sensitivity. Also potting can be caused by a lot different reasons and the most common one is hormonal imbalance.
Hi my period was last the 17th last month (October) met with my partner 2nd November I’ve got Strange feels and I’m late with my period could I possibly be pregnant??
Hello Sam, since you were on yor fertile days when you had sex, that is a possibility. I recommend taking a test if you had unprotected sex.
hi , last day of my period was around 28th July. On the 12th of august I had sex. On the 24th of august when I expected my period they don’t come and 2 weeks later nothing, yet I get cramp like pains often.
Hi Sandy, have you taken a pregnancy test? While it would have appeared to have been after your fertile period, it depends on how long your cycle is, this is assuming that it’s a 28 day cycle. Take a pregnancy test.
Hey, I am Rita, I saw my last period on 5th of July and I tested pregnant, how many weeks am I now?
Hi Rita, based on the calculator you are due around April 10, 2020, which means that right now you are about 7 weeks and 5 days pregnant. Congratulations!

Hi Jane, that would have been during your fertile period so take a pregnancy test.

Hi Rebecca, take a pregnancy test.
Hi the first day of my last period was 21st of January and my cycle is 28 days. I had unprotected sex on 9th of February. Could that be my conception day?
Hi Linda, your fertile period was most likely from around the 31st of January to February 8th so I would say that the 9th was most likely be your conception date.
Hi I last saw my periods on February not sure which date and I’m pregnant how far I am
HI Lucy, without the date of the first day of your last period I can’t give you an estimate based on the calculator. If you had your period for example on the 15th of February you’d be nearly 26 weeks pregnant give or take a few weeks depending on when your period was. At this point I would recommend seeing a doctor if you haven’t already considering you are more than halfway through your pregnancy. Good luck and congratulations.
Hi I last saw my periods on 26th March 2019 and am pregnant how many weeks am I? I under go 28 days in my cycle.
Hi GLiceria, congratulations. And you would be 18 weeks 1 day as of today which is the 31st of July.
My period was 29th may 2019 and I spotted two weeks ago could I be pregnant?
Hi Sophie, you could be considering you’re already late for your period which you should have seen your period around the 26th of June. At this point take a pregnancy test.
Hi sir I’m Cheryl I have a question my period may 23-27, 2019 until now no period..possible I’m pregnant …thank u
Hi Cheryl, did you take a pregnancy test, at this point you are nearly 2 weeks late.
I last saw my period on 26 February and I did pregnancy test it shows 2 line so that means I’m pregnant?
Hi Dineo, if your last period was on February 26th and you got a positive pregnancy test (review the instructions on the packaging of the test that you used), you would be 13 weeks pregnant at this point. I recommend making an appointment with you doctor to ensure that your pregnancy is going along well. Congratulations.
Heii my last period was on 6th of December when is my due date
HI Nothabo, according to our calculator you would have conceived between the 16th and the 24th of December.
My last period ended on 2 December. I had regular mp of 28 days cycle. when can be due date
Hi Purity, based on a first date of your LMP being roughly the 28th of November, your EDD would be September 4th, 2019 or somewhere around there. That being said you should have seen your doctor already to make sure everything is going well with the pregnancy. Congratulations and good luck!
Last period was 30th December 2018, since Jan 5th 2019 to 25th Feb had unprotected sex though not every day. 30th n31st morning hours received light periods just morning hours and it was gone. After some days I tested for pregnancy and found out I was. My problem is I always have irregular periods how do I know wen I conceived?
Hi Monica, have you been to the doctor yet and gotten your scan? They will initially base your EDD (estimated due date) on your LMP (last menstrual period), however it will be more accurate when you get your ultrasound and they can determine what the actual week size of your baby is. Then you can calculate when you conceived. Congratulations and good luck!
A full-term pregnancy usually lasts between 40 and 41 weeks. although 30 percent of pregnancies continue until the 40th week, most of them continue only till the 38th or 39th week.
Hi my first period last month is march 2 and it’s already 7th of april and im not yet started my peruod this month Can i be pregnant? But i feel tye symptoms already 3 days ago that i will having my period but until now not yet.
