20 weeks!

Lunar months start at 17 wks and the so-called 9 months of pregnancy method starts at 18 weeks.

Hi pari: you will hear something different from everybody and from every book you read, I'm not sure if anybody conclusively has the right answer! Although I think Suzie's answer is what I've read the most to be accurate. But here's how I always think about it: If you are 16 weeks and 4 days pregnant, then you have completed 4 full months (16 weeks) and are now 4 days into your 5th month. That's the only way it makes sense to me, but I'm not claiming it's the technical answer!

Hi there, no. of weeks does not = no. of months, Eg. I am 20 weeks pregnant but I am only 4 and a half months pregnant, My baby is due on the 9th October, so on the 9th June I will be 5 mths pregnant (23weeks) , On the 9th July I will be 6mths pregnant (27weeks) ect......

I think it depends how you figure it. I'm not sure what the docs go by, but in calendar months (9 month method) you would have to figure every third month to have five weeks in it, and in the lunar calender, every month is 4 weeks, so you are technically pregnant for 10 months. I just go by weeks because everyone knows the standard is 40 weeks.

I dont go by months its too confusing and thats why doctors dont use them. When a woman says "im five months pregnant" Its not accurate because your not really 5 months until you have COMPLETED that month. 20 weeks is only 4.5 months (20 weeks is half way there and half of 9 months of 4.5) I stick to the weeks and days.

Everybody says different but a lot of my books say 20 weeks.

Fifth month STARTS around 17.5 wks. Just take your due date and go backwards. My due date is Sept 5th, so my 5th month STARTED April 6th...When someone asks me, I just say I am about...how ever many months or right now 5 1/2 months. About just generalizes for everyone but is good enough!!
