Hi. I'm 17 and have PCOS. A week ago,5-6 after my period stopped, I did a quickie (it was my first time). he only went halfway in for a few times. Could I be pregnant? For the past three months,I've already had regular period but they were way lighter than my periods before. I also started duphaston (10 mg) yesterday. My doctor told me to take it once a day. Could i be pregnant? And if so, how early can I take HPT? Please help me .
