Progesterone pills

Hey ladies!!

With my initial blood work around 4 weeks my progesterone level came back at 17 which was perfect. At my 6 week appt my OB decided to recheck the progesterone and it came back as a 9 so now I’m on a supplement every night. I did have an ultrasound at my 6 week appt and we saw a bean with a heartbeat. I am so nervous to miscarry has anyone else had to go on progesterone and still carry out a healthy pregnancy? 😢
