Okay , I had already gotten my period this month which was last week . It was like my normal period , normal flow and lasted for about 5 to 6 days. So about four days after my period ended I got this sharp cramp like pain in my lower tummy and after about 3 or 4 minutes after I started bleeding again but bright red and sort of heavy . I don't know what it is and I'm worried , is something wrong with me ?
