This is the second time am taking prostinor 2, the first time I took it, I bled after a few days, and later I still had my period for that month. Now this time it's been 12 days after taking the drug and I haven't experienced any bleeding or spotting, I believe I was ovulating when I had unprotected sex, I took prostinor 2 about 28 hrs after sex. Am so scared, pls help ...
