Hello, i had unprotected sex but took ipill after that , i am getting treatment of pcos from last 3 years , this time my periods were 10 days late but its not stopping even after 15 days .. Very little thick brown blood is coming. I had gone through pelvic scan and it shows that my ovaries are bulky in size n pcos is still there. Doctor gave me medicine which will stop bleeding in 3 days , but from few days i m feeling lot of stress on my lower stomach .. N i m agraid of it, is there any chance of side effect of ipill or any risk of pregnancy??? Please assist me..
