  • Well, it's every 4 weeks. So by the time you are in your 4th week, you are at the start of your second month. At 8 weeks you are at the start of your 3rd month. So at 9 weeks you are 2 months and one week.

  • There are 4.33 weeks in a month, so 13 weeks is 3 months (or a trimester).

  • The month is 4 full weeks, 28 days instead of 30 or 31 like in a calendar month.

  • I agree with dragonriderMD 13 weeks is one trimester aka 3 months =]

  • Month1: 1-4weeks, Month2: 5-8weeks, Month 3: 9-12weeks. Month 4 is when it is 5 weeks. Month 4: 13-17weeks, Month 5: 18-22weeks, Month6: 23-27weeks, Month 7: 28-31weeks, Month8: 32-36 weeks, Month 9: 37-40weeks. Some months are 4 or 5 weeks long, it's weird. This list is from the hospital too.

  • I think what you are confused about is that at nine weeks you are IN your third month, 2months and 1 week. But you won't BE 3 months until 12-13 weeks. (depending on if you are going by months or trimesters)
