second miscarriage

Ana

I need advice!? My BF and I just decided to start TTC in June. I was lucky and got pregnant on the first try. unfortunately I miscarried July 26 😔 Doctor thought possible Chemical pregnancy.... We decided to wait and started trying again last month. unfortunately I miscarried again October 30. Doctor said atleast I'm getting pregnant. but unsure why I can't carry full term. they think possible low progesterone? anyone have this happen to them?
