Actually there are 4.5 weeks in a month, and that makes pregnancy exactly 9 months. So you're half a week from 5 months:)
So you just passed 5 months and you're 4 weeks away from 6 months
13weeks = 3 months in the USA pregnancy language
well theres 4 weeks in a month...
5 and a half. 4 weeks equals a month
