Hi. I'm 18 year old. I had a small surgery for having normal mensuration a year before. It seems that I had a block somewhere in my reproductive system causing blood to store for years and the block was removed soon. I had sex with 2 months ago. Its almost 2 months and a week after the intercourse and I still have not got my period. After the sex he did not ejaculate inside the vagina or anywhere near. I found drops of blood a few time usually brown in colour. I took a pregnancy test from a local lab and came negative. After a few days I consulted a doctor and was given a medicine name medroxyprogesterone acetate ip .now I still have not got my period .the spotting is gone but white discharge can be seen. Im not in a state to be pregnant now. Is there any chance that I am pregnant? If not what is the reason why I'm having missed period. Also while I had my intercourse I had bleeding as well. I have not told the doctor about the intercourse I had because she is someone I know. Please help with answers.
