Well, 40 weeks = 280 days. 280 days / 30.5 (average days in a month) = 9.18 months. So it’s just over nine months. But since pregnancy is dated by the life of the EGG and not when it was fertilized, you are already about four weeks pregnant by the time you miss your period. So only 36 weeks go. Not 40.

For example, I found out I was pregnant on 9/11/12. I had my child on 5/20/13. I knew I was pregnant for about eight months total.

jordanl1027:  I have googled that too! One thing to remember is that you may not be successful the first time. We are planning to start TTC November 15th which would mean a late August baby at the soonest if that helps. I really am hoping that my cycle is a little off and we get a September baby.

jordanl1027:  koi424:  These are also great estimated due date calculators. Especially if you know what day you ovulated on. In the first one, you can even figure it out by what date you’d like to be due in the future and it will tell you what day and month you should get pregnant for that to happen.

The 40 weeks of pregnancy is calculated from the beginning of your cycle, so if you know your cycles fairly well, you can estimate due date pretty good from the due date calcualtors. If you know your ovulation day you can be even more accurate. They go by the 28 day cycle with ovulation on day 14. For me I ovulated on day 21 so that changed my due date by a week.

As for myself, my pregnancy cycle started July 10th, 2013, I was due April 22nd, 2014 and gave birth 10 days after that on May 2nd.

I created this little “chart” that’s very rough because it all depends on your conception date. But here ya go anyway 🙂 C: conceived D: Due

Pregnancy calculators are going to be your best bet, especially if you have a pretty regular cycle and can project when your cycle will start each month.  It’s important to remember that when you’re due will also depend on when during the month you ovulate (so it’s not a straight month –> month calculation) – for example, I ovulated July 14, and I’m due April 3 – there are other ladies who got pregnant in July who are due in March.

Use the online calculators!  My conception date (estimated based on ultrasound) was July 11 and my due date was April 3.  Baby came (via induction) April 10.  I think the beginning of that cycle was June 25 (so the first day of my period).
