Figuring out how many months pregnant you are is a daunting task for many women!    That’s why it’s sometimes much easier to just stick with how many weeks you are instead.  Something doesn’t seem quite right when you superficially think about connecting pregnancy weeks with months.  Afterall, if there are 4 weeks in a month and 40 weeks in a pregnancy, doesn’t that equal 10 months?? (40 weeks / 4 weeks = 10 months).

If you use a conventional counting of 4 weeks = 1 month (such as week 1-4 is month one, 4-8 is month two, 8-12 weeks is month three) you’ll soon discover that the 9th month will end at 36 weeks and week 36-40 will be your 10th month! Strange, huh? That’s what makes it so confusing and why going by weeks is much easier to keep track of.

But normal non-pregnant people don’t like to hear “I’m 13 weeks” or “I’m 27 weeks!”.  They like to know which month you are. It took me a while to completely figure out how it worked as well.  But alas, I did!  

Here is a timechart to help you convert your own pregnancy week into the correct month!  Remember, the determination is made based on counting the weeks from your LMP (last period).

It’s not based on any medical knowledge - I just came up with this based on the fact that a “month” is actually 30-31 days long (4 and a half weeks…. four full 7 day weeks  (28 days) plus 3 days, which makes a half week).  A full term pregnancy is any time between the 37th and 42 week, so I calculated the 9th month to last beyond the 40th week.

PREGNANCY CHART:

Month One = Weeks 1 through 4.5 (4.5 weeks)

Month Two = Weeks 4.5 through 9  (4.5 weeks)

Month Three = Weeks 10 through 14.5  (4.5 weeks)

Month Four = Weeks 14.5 through 19 (4.5 weeks)

Month Five = Weeks 19 through 23.5  (4.5 weeks)

Month Six = Weeks 23.5 through 28 (4.5 weeks)

Month Seven = Weeks 28 through 32.5 (4.5 weeks)

Month Eight = Weeks 32.5 through 37 (4.5 weeks)

Month Nine = Weeks 37 through 42  (5 weeks)

Another way you can offer up to people how many “months” you are, is to just go by the calendar month.  For instance, I was fortunate that my LMP ended the last day of July, making the whole month of August, 2007 my “first month” of pregnancy.  Whenever someone asked how many months along Iwas, I just did a quick mental calculation of how many real months had passed.  (September - Month 2, October - Month 3….March - Month 8, etc.).
