I have my regular period. Had my last period last july 7. Had sex around 3am last july13. Had three rounds, and had him penetrated inside of me on the first round. So i took nordette on july 15 8pm. And another set on july 16 8am. We are not sexually active, i dont want to get pregnant because i just gave birth 5months ago. I had vaginal bleeding 6 days after taking up nordette. It took 2-3 days. Based on my given details, is there anything i should be worrying now? Im expecting my period on august 4. Please help. Thanks
