Very dumb question about calculating months

jenmarshall88

Ok forgive me for my stupidity. But I seem to be getting mixed responses from family about what month I am pregnant. I mean there are 10 months to a pregnancy technically with how they calculate it. 40 weeks, 4 weeks to a month=10 months. Now I am 21 weeks pregnant. 4 weeks=1 month, 5-8 weeks=2 month, 9-12 weeks=3 month, 13-16=4 month, 17-20=5 months. So that would mean I am in the beginning of my 6 month, am I right? So when people ask me how many months I am, my response is 6 months. But yet my fiance and some people in my family tell me I'm 5 and I've even been told 4. Even when I explain my thinking of calculating it out. Please explain to me because it is making me feel QUITE dumb. And also make me feel better that someone else has weird confusion about this and that I'm not alone

Actually on average each month has 4.33 weeks, so you could divid your week by 4.33 and get a more accurate number.

So I am (just about) 20 weeks, I would be 4.6 months.

I know exactly what you mean. Here is what the book I got from Dr says:

1st month 0-6 weeks

2nd month 6-10 weeks

3rd month 10-14 weeks

4th month 14-19 weeks

5th month 19-24 weeks

6th month 24-28 weeks 

7th month 28-32 weeks

8th month 32-36 weeks

9th month 36-40 weeks

Hope this helps.

To keep it simple, I either go by weeks, or when I say how far I am in months I go back from my due date of August 20 with that as being 9 months. So, on March 20 I was 4 months, now I'm a bit past that.

if I were going by months, I would say the same thing you do. Technically speaking, since I'm 18 weeks, I'm in my 5th month of pregnancy, but won't be 5 months for another 2 weeks (if that makes sense). But I just tell people I'm 18 weeks whenever I'm asked.

Don't feelt dumb, I am a smart person and I've wondered this several times!  it's weirdly complicated, yet simple too!

this. you aren't 6 months pregnant until the END of 6 months. Before that you're 5 months, 5.5 months, etc.

I think that you're five months pregnant, meaning that 5 months are done, but you are working your way up to six months so you are "in your 6th month". Did that make any sense at all?

Think of it this way.  When you are 25 years old plus 2 months, do you tell people you are 26 years old?  No, you tell people you are 25.  So, when you are 5 months (completed months), plus 1 week, you are still 5 months pregnant, not 6 months pregnant.

True, I think I'm just eager to be further along than I am

Yep, it's funny, I have noticed in various books or online, the weeks are different for each 'month'. In most of them it seems like they add an extra week for the both the 4th and 5th month!

Mish2g

I'm right where you are, yet I calculated 5 months (20 weeks divided by 4weeks/month = 5 months) HOWEVER, there's a whole system that makes no sense to me! What to Expect When You're Expecting had me at 5 months 2 weeks ago...there's a website that spells it out for you, but I disagree with it.

So...I tell people I'm 5 months (21 weeks now)  and when I'm 24 weeks, I'll tell them I'm 6 months.

I don't think it's a dumb question at all.  This is something I go by and visit often.

I thought about this a lot and I figured this was the BEST way to look at it.

They calculated my EDD based on the first day of my last menstrual period.

This was 10/26. So now on 3/26 I was 5 months exactly. This would mean that if pregnancy was exactly 9 months I would have the baby on 7/26. Which is pretty close to my EDD of 8/2.

Hope this helps!

PS- So now I tell people I am just over 5 months. Around 4/13 I will say I am 5 and 1/2.
