Is there a chance of pregnancy? My OB injected me a norifam last feb. 06, 2018 and I got my period last jan. 27,2018. I have an irregular period since then. My last period was on feb.27,2018 lasted for about 8 days and that was in 7th date of March with spotting. We had sex with my husband in that day 7th with still spotting. He did not ejaculate outside thinking that it was safe after menstruation. My next visit for norifam injection will be in March 6-10 but I failed to have it due to my hectic schedules. I am 8 days delayed now with no symptoms of pregnancy and I even tried to have a home pregnancy test 4 times and still negative. My question is. Do i have chance of getting pregnant or missed a period could be a side effect of norifam injectable? Thank you for your answers doc.
