2nd Trimester

If I am 20 weeks, how many months am I?

I turned 20 weeks today (whoo hoo!!).  I am trying to figure out how you count how many months you are based on weeks. 

My co-worker said 4 weeks does not equal 1 month in the pregnancy world.  I would think since I am 20 weeks I am 5 months - 2 weeks into being 5 months so I could also say I am 4.5 months. Is this correct?

  • I just tell people in weeks, if they look at me funny I round it or say about four months.

  • 17.5 weeks is 4 months, every 4w3d is one month.

    If you punch your due date into the right hand side of the screen, it will tell you how far along you are in months.

  • If you're 20 out of 40 weeks in, you're halfway through your pregnancy, or about 4.5 out of 9 months. Each month is >4 weeks anyway, in pregnancy or otherwise (except for non-leap-year Februaries).
  • I'd tell people about 4 1/2 months.

  • 4 1/2. You're halfway done, half of 9 is 4 1/2. But I just say weeks myself.

  • seeing how 20 weeks is half way through 40 and they say you are pregnant for 9 months I would say 20 weeks is 4 and a half months.

  • Pregnancy months are generally counted in Lunar months, which are 4 weeks each.  That is why they also say you are pregnant for more than 9 months.

    But medical people will always count in weeks, because it's more accurate.

  • I think it's easier now to count back from your due date and assume a 9 month pregnancy.  My EDD is about 4 months away so I'd say I'm about 5 months if someone asked.
  • 4.5 mos.

  • Depending on who I am talking to, I say weeks or months.  If its a woman who has had a baby I say in weeks.  Men or people who don't have kids I usually say in months.

    Even though it doesn't work out perfectly, in my head 4 weeks=1 month, so 20 weeks would be 5 months.

    They say you are pregnant for more than 9 months because 40 weeks is actually 9 months and 1 week.

    But a lot of websites, books, etc. will tell you you are "actually pregnant for 10 months!"  Which is true, if you are counting in lunar  months.

    but keep in mind it's counted from the LMP, so the first 2 weeks, you're not pregnant yet
