I am 19 years old and on the Depo shot. I feel burning and discomfort during intercourse. I also have cramps at times and very light spotting. Haven't been to the doctor yet but wanted to possibly know what's going on with my body before hand.

Try using a good lubricant and get turned on prior to intercourse. The spotting and cramps can happen if there is deep penetration by your partner and the cervix is hit. Try positions that limit this
