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:

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.

My last period was on July 21,2020 and my husband and I had an unprotected sex on July 28 and again on August 1,2020. Then on August 3,2020 he came inside of me. I am usually a 32/35 day cycle so now my period is expected to come on August 21,2020 but I’ve been noticing my breast tenderness and I am very moody at times and bloated as well. I also took multiply cheap pregnancy test and they came back with a very faint line. Well that what it look like I’m not sure. But I do know that I ovulated on August 10 base on MY FLO APP. SO please help me.
Hello Ashira! Your estimated conception date is around Aug. 3 – Aug. 18. So if your husband didn’t withdraw on on Aug. 3, it is possible that you are indeed pregnant. However, your symptoms that include breast tenderness, moodiness, and bloating are also pre-menstruation symptoms. As of writing, your menstruation is yet to come so you can wait for a few more days and take the test again to confirm.
My last period was on the 18th of April. I had sex on the 30th of April and my monthly cycle lasts for 34days. I did an ultrasound on the 24th of July and it was 12wks and 6days. I’m confuse. How could that be? Does it mean that ultrasound gives fake weeks of pregnancy? Please calculate for me. Because it’s causing a lot of problem. Please explain more to me
Hello Phina!
Your ultrasound results are not giving you wrong information and they are actually correct. Since your last period was on April 18 and you had unprotected sex on the 30th, it is likely that you can conceive because you were on your fertile window. I hope this clears things up for you.
My last period was 15th April and I missed my period may how many months am I now.
I’m 7 weeks pregnant but when I went for a scan, they didn’t see anything aside my fibroid. I started spotting too. I was asked to come in 2 weeks time for another scan.
Is there a cause for me to be worried? And it feels like I don’t feel like how I used to feel when I got pregnant.
I’m not really experiencing any pregnancy symptoms now .
I’m worried.
Hi
I took my last shot in January 2020 and never went back for my shot. Earlier this month i got my period but it was not that heavy and dark as expected. I feel naseuos and bloated and breast are extremly sore. could i be pregnant.
Hi. My period was last seen on 18 March then did a medical abortion on 20 April. please when next should I be seeing my last period and how long was the pregnancy before I had the medical abortion..
Hello, you should expect your period 4-8 weeks after the abortion. You were in your 5 weeks of pregnancy when you got the abortion.
Hi I’m just wondering my due date is 29th of July 2020. I’m just wondering how many weeks am I, as i can’t use the cycle calculator. thanks!
Hello Deirdre, weeks are calculated by the last day of your last period, Pregnancy often lasts 280 days or 40 weeks from then. You should be 24 weeks pregnant on the day you posted the question.
Hi the first day of my last period is 29th September and I had sex on 12th October
I am tested positive for pregnancy
but how do I know my due date
Hi, first day of my last period was 3rd of November, I took Azithromycin on the 18th, and after I had unprotected sex on the 19th, with no ejaculation, and I had catarrh on 21st and an irritated uvula, I took unbranded amoxicillin and vitamin C, and I had a cough on the 23rd and i took emzolyn syrup, and on the 28th I started bleeding, three days before my expected period, I took a pregnancy test but it came out negative, please am I reacting to the drugs or is it something else?
First of all, please re-take the pregnancy test since it looks like you’re 27 days off your date of menstruation.
The cycle can be delayed in the case of antibiotics use for a really long period of time and due to infectious conditions both of which are positive in your case. Visit your OB-GYN and get an exam done and stop taking antibiotics without the prescription of a certified doctor.
