I’m on the depo shot probably week 9/10 and I’m having head aches, constipation, nausea, stomach cramping, back pain, and light/medium bleeding. Could this just be because I have my period or is the shot/ something else causing my problems? This is my first “period” on the shot since I bled the whole first month with no break. I just feel incredibly sick and don’t know if it’s from the shot or not. I’m also a teenager so I could always talk to my mom about changing my form of birth control
