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.

hello..my last period was january 29-31,2018..we have sex last february 11,16,and 18..and my period did not come yet..am i pregnant?
Hi Avryle, it’s quite possible that you are. Did you take a pregnancy test? If not, I would recommend that.
Hi my name is Ayo I have sex on the 18 of December and am 7 weeks 7 days pregnant is possible is for my partner
Hi Ayo, I don’t really understand the question you are asking? Is it possible that it is your partners? I mean if that’s the question that really depends on you and when you had sex and with whom.
Hello. My last period was on January 26 2018 I have always had regular periods. My period was due feb 22 however I am now 4 days, late I took a pregnancy test and it was negative did I test too early
Hello Leashia, you might have tested too early. Retest for pregnancy 7 days after your missed period.
Hi I am twelve weeks pregnant now ,is it ok to travel abroad around June end
Hello Luxmi, yes it should be fine for you to travel provided that you are not high-risk.
I am a 23-25 days cycle and we have sex last December 26,2017 and i Got my period Last January 5,2017 and ended january 9, 2018 and it came again January 27,2018 and ended january 31,2017.. is it possible to get pregnant by Febuary because my period didnt come yet and i am already 3 days late in my period calendar! Need help thanks!
Hi Princess, Your most fertile period was from the 2nd to the 6th of February, so if you had unprotected sex at that time, it’s possible that you could be pregnant. I would recommend getting a pregnancy test as that is the only way to be sure.
We have Sex Last December 26,2017 and my period come Last January 5,2018 and January 27,2017 is it possible to get pregnant by February. Because im alteady 4 days delay in my period calendar my period didnt visit yet
Hi Rinces, if you have a shorter cycle, then you could become pregnant (assuming you had sex this month), but with a 28 day cyle you woulnd’t be expecting your period until the 24th of February. But if you are late, take a pregnancy test to be sure.
I had sex last june 10, 2017 and I got pregant, when will be my due date?
Hi Merian, I would imagine that you have been going to the doctor and having ultrasounds in which they can tell you exactly when your estimated due date is based on the size of the baby and growth, last menstural period etc. however based on the calculator and a rough estimate of you period your looking at a due date somewhere around the 8th of March, which is less than 2 weeks away. Good luck!
My partner had her last period on the 18-19th of August 2017 And her due date is around May 19, 23 and 26 2018. I wonder which month she got pregnant, end of August or beginning of September? We had sex like few days after her period, she went out for a medical travel, and had sex with a guy on September 1st. I’d appreciate some help. She’s roughly around 26 weeks and 5 days.
Hi Jackson, Based on the due dates that you gave, she could have gotten pregnant anywhere from having sex from 8/21/17 through 9/2/2017. So there is wide range based on the three dates that you gave. So it could be either. Honestly that will have to be something to consider for you and your sanity when the baby is born becuase the only way to know for sure is with a DNA test. Good luck!
my last period day was 14 December 2017 , my cycle is 31 day, my first week of January 2018 is when I had sex and fell pregnant! Would I still count that I’m nine weeks?

Hi there Liza, please take a pregnancy test 7 days after a missed period.

Hello Heena, read the following link as it relates to abortion: https://womanjunction.com/how-many-months-after-being-pregnant-is-termination-an-option/

Hello Kierra, since your symptoms are so obvious you could take a pregnancy test. However the most accurate time I would advise is 7 days post your missed period.
my fertility window is January 19-24 we had sex on 20th and 21st. is it possible for me to get pregnant?
Hello Regina, yes it is possible for you to get pregnant.
