"im 17 years old, 5&#039;4 and weigh 113 pounds. got my first injection on may 22nd. first few days was fine, got it while i was on my period so it was immediately effective. first week was fine but after a while i began spotting and since then i have been on a constant period with occasional cramps. i already suffer from some anxiety issues which depo-provera has intensified but i expected this. feel dizzy when i&#039;m laying down to go to sleep but its gone by morning. no change in sex drive but i&#039;ve noticed most people&#039;s decrease. the site of injection hurt a little for 3-4 days but now i can&#039;t feel it. have little energy and can&#039;t walk to school anymore because i&#039;m constantly too tired. wont be getting this injection again, going to try nexplanon implant."
