Recently got the shot maybe about a month, I asked the nurse who administered the shot when I could have unprotected sex and she said “instantly there should be no issue.” Well I had sex that same day…. My period instantly stopped and besides being slightly moody, there has been no issue. Now I am bleeding and it is not really like a period flow but to me it seems heavy for pregnant flow…. I took a pregnancy test and it said that I was not but maybe it was too early to tell not being quite a month and all. What I was wondering if anyone knows what is going on? Should I just go to the clinic and get checked out? Just opinions would be nice! Thank you!
