I am on a Implant called "nexplanon" but recently I have been waking up nauseous & even waking up from naps nauseous getting this cramp on my right side of my abdomen usually gets worse at night I always feel bloated & I have been dizzy when standing up I've always got a little light heads sometimes but lately it's been worse I literally get flashes & cants see for a couple seconds. I am not an inactive person it usually doesn't take much for me to walk up a hill but I get so tired so quick now and it don't seem normal to me. Help any answers on what this could be ??
