Bleh..

So for about 2 weeks now going on 3, I've had a really watery mouth and nausea, but never the urge to vomit.. Its really weird. The only time it gets really bad is usually right when I wake up or after I eat or drink something. I've never experienced it for this long before. I also experienced really, and mean really really sore breasts about a week ago for a week straight. I really don't think I'm pregnant, it is possible though. I've been off depo for 2 months now, no full period yet just a week of very light spotting. Do you think it could be withdrawal from the shot? Can anyone else relate to the symptoms after coming off depo?
