I'm on the depo shot and have been for about 2 months now. I had unprotected sex about 2 weeks after the shot. Within the pass 3 weeks I have been getting more and more pregnancy sign, for example: Peeing like crazy, the most crazy and weird food cravings, gaining slight weight even though trying to maintain it, horrible horrible mood swings and being extremely emotional, tired all the time even though at night it seems like I just can't sleep, and etc. Two days ago, around 3am I got the HORRIBLE expanding, and painful feeling in my stomach, sorta like a period cramp but only about 100 times worst, I went to the bathroom and noticed that I was having a pink watery looking discharge, and within a day it had to brown and now back to pink, I wore a pad even though nothing was getting on it and really I can only see it when I wipe, even though the terrible cramps are still there. My periods are usually extremely heavy and I've never had anything like this before, and I honestly don't feel like its any sort of menstrual period. I took a pregnancy test about 2 weeks ago and it came out neg. Yet the signs are getting worst and worst. I'm not sure what the bleed is, or what it could possibly be? Pleasssse help!
