Your technically pregnant for 10 months if she is due in September then she conceived end very end of November maybe beginning of December

See the doctors said September for her but that's 10 months right?

Deff due in August my last period was in November and I'm due August 24

If she hasn't had a period since then she should've already been to the dr, and she would have an accurate due date

she's about 20 weeks. due date would be late August

I'd say 19-20 weeks I think

The last day of my period was December 15 and I'm 17 weeks

I'd say around 20 -24 weeks.

Ha my bad yes the last day of her period

There are calculators online as well as apps to calculate due date.
