Cramping and spotting on depo shot.....

imhere

Ive been having cramps for about a week. and yesterday ive had spotting. Im not due for another ahot till the end of August. Ive had unprotected sex in march. But all the tests were negitive. And i highly dont think im pregnant.

I hardly had any cramps when i was younger. So i have no idea what cramps are like. The cramps are in the middle of my stumach. And switches to my left and right ovary. Is that normal.
