So I'm on the Depo shot. have been since April. but in the last month I've gained at least 13 pounds and have been experiencing some pretty harsh cramping every once in a while. some very light spotting happens after sex which doesn't happen often, and I have this Milky White CM that just showed up. I know I for sure do not have any STDs. been with the same guy since April and got checked before I got the shot. I've also been extremely irritable and very short tempered lately. i bought 2 tests tonight and plan to take them tomorrow. what do you all think ?
