you're 6 months! 7th month starts at 27wks & 8th starts with 31.. 9th month starts with 36.. my dr. gave me a chart that ive kept through all my pregnancies, also you can google "weeks and months of pregnancy converter" ... hope it helps
How I do It, Is
4 weeks = 1 month
So you'd be at 6 months, one week, and one day to be exact.
I always divide by 4 but to tell ya the truth everyone seems to go by weeks anyways! :)
