I got the depo shot for the first time on February 18th 2015, my period had started on the 13th. My boyfriend has finished inside of me too many times to count since then. My periods are always on time and always heavy. I'm 7 days past the day I was supposed to have my period, no blood at all. My boobs have been sensitive, so much so that my boyfriend took notice. I took a pregnancy test on the 19th and I had a very faint pink line for the first 2 minutes of waiting but when my timer for 3 minutes went off the line was gone. It wasn't the first pee of the day, more like the 4th lol.  Is it normal for the Depo shot to immediately stop your period or should I take another pregnancy test because it may have been a false negative?
