9 wks with Low Progesterone ?

Shelby

Went yesterday to have my 9 week ultrasound and the baby’s heartbeat has went up from 122 at 6 weeks, to now 182. Everything looked good, only thing was my progesterone was a tad low she said so I am now on the pills 100mg. I cant help but worry something could go wrong. Has anyone else had this problem? Thanks so much.
