i have taken 4 at home pregnancy tests and they all came up faint positive and the digital one came up pregnant 1-2 weeks i am 4 days before my missed period. I had a blood test and the results came back with a hcg level of 12. my doctor has started me on progesterone supplements and i get another blood test tomorrow. Should i be worried about a miscarriage? i have been ttc for 3 years with pcos and with diet i changed my blood work to normal and then found out i was pregnant .. is there anything i can do other than just wait??
