I went in Monday for my first prenatal appointment & got my ultrasound and bloodwork. We are having TWINs! I was supposed to be 8w2d but the babies measured 6w1d- my first kid was measured about a week behind at her first ultrasound. The doctor saw both heart rates on the ultrasound, but I got a call today that my progesterone level was low at a 14.1 I think. Typically should be about 18-20, so I am starting prometrium tonight and that should hopefullyhelp boost my Progesterone. Has anyone had a similar experience with a good outcome/full term pregnancy?
