If I'm 23 weeks pregnant how many months is that?

just starting your 6th month. 23-27th week is 6 months. Just like in any other month you don't get into the second week of January for example and change the month. You have four weeks roughly but keep in mind pregnancy terms are not the same as calendar terms. You're months are actually a little longer than four weeks each. Technically you are pregnant for 10 months not nine but since the weeks are divided differently its 9 months of being uncomfortable!
