Hi everyone, I have a question, my last period was the first days of march, I had sex 4 days after and took the plan b... two weeks later i went to the clinic and had already 2 pregnancy test both were negative... and yesterday I just got the depo shot for which I waited 2 weeks..but still haven't gotten my period, is that normal.? and does the depo shot work already. Im afraid to get pregnant, nobody told me I had to wait certain days after yesterday..I havent had sex since the 10 so Im a little skeptic??? how many days should i wait since i just got the shot yesterday( no period yet and not pregnant) thanks!
