It was weird, it was the lightest period I ever had but I would cramp on my right side felt like in my ovaries 😩😭 it was painful it did that the 2nd day of my period... now I would bleed light then not see anything for the rest of the day. It is now the 27th and I still have issues😭. My head been hurting for days, my lower back aches, and all I do is sleep. Could anyone help me with that’s going on?
