Hi, I have been on the depo shot now for around 2 months. I had two weeks until my next period and missed it then started spotting brown a few weeks later that has been lasting 3 weeks now. I also have to pee every half hour to and hour without drinking anything, I keep burping, sleeping more than usual, but also waking up earlier, I cant eat without feeling sick, my back and sides are soar, and also crying a lot over small things. Is this from my shot or is something actually wrong. I have also been having unprotected sex and the last time after he finished the lower part of my stomach hurt for the rest of the day and it took place in the morning.
