I am so confused when i start to think about what week i am in or what month. How do we calculate the weeks so that i am correct when someone asks me How many weeks i am. Also what is the break down for each trimester or month of pregnancy. ↓

I believe it starts the day you are supposed to get your period. Then every 4 weeks is a month. You are really pregnant 10 months if you look at it like that. I know it's confusing, go to babycenter.com and enter your LMP and it should tell you, also it will send you a weekly newsletter so you get info on your week! Hope that helps! ↑

What helped for me was taking a calendar and looking at which day my last period started was (which was on a tuesday), then on every Tuesday after that marking the number. I know that every Tuesday marks the first day of the next week. Like tomorrow, I start week 6. If you're not good at math then you can mark down a new month each 4 weeks also, that way you don't have to take your weeks and divide by 4 to figure how far into each month you are. ↑

Yes both are right... except I did the babycenter thing plus a few other sites and one emails me saying your in week 13 others say week 11 others say week 12... very confusing! ↑

I went from my due date and counted back on the calendar and marked the day each new week began cause different site says different things ↑

I went to www.google.com and typed in pregnancy calculator. Then you can type in your due date or the first day of your last period. And it can give you the date ↑

A full term pregnancy is 40 weeks. You can figure out what week you are by counting back from you due date.

FIRST TRIMESTER
Month 1 (weeks 1 - 4)
Month 2 (weeks 5-8)
Month 3 (weeks 9-13)

SECOND TRIMESTER
Month 4 (weeks 14-17)
Month 5 (weeks 18-21)
Month 6 (weeks 22 -26)

THIRD TRIMESTER
Month 7 (weeks 27-30)
Month 8 (weeks 31-35)
Month 9 (weeks 36-40) ↑

I just went to the Doctor yesterday and had this explained. Week 1/day 1starts on the 1st day on your last period. so, the 1st day of my last period was June 2nd, so I am mid way through my 7th week. Then you just count 7days to calculate your 40 weeks from your last period to get your due date. Hope this helps!! ↑
