I have had 3 miscarriages since having my 15 months old son. Two were before 5 weeks and the most recent was a MMC at 10 weeks. I also had three early miscarriages in the year prior to having my son. My OB has offered to run labs for me to investigate why I've had so many losses. I've already had my thyroid checked and all the labs that get done during pregnancy (CBC, RH factor, blood type, vitamin levels) and nothing has come back unusual except that I'm vitamin D deficient. I have PCOS and endometriosis as well. From what I understand, whatever lab work they're doing, I haven't had done before. Does anyone know what tests they'll be doing?
