I'm 23 and my periods are regular.I'm sexually active and I don't exercise at all.I work two jobs.On October 16 I started my period.During my period I have a lot of cramps and its very heavy.I use at least 8 pads a day.It lasted til 20.On October 23rd me and my boyfriend had unprotected sex.Then on October 29th we had unprotected sex again.I'm sure round October 29th I was ovulating.On November the 11th I got this heavy bleeding.I dont know if it was my period or breakthrough bleeding.This time I didn't have any cramps and the bleeding was light to where I only had to use about 3 pads a day.That lasted til November 14th.By the morning of November 14th it had completely stopped.So I went on with my day.November 16th came along and I notice that when I wipe after using the restroom I have dark blood on the tissue.So I put on a pantyliner thinking I was bout to start bleeding again but there was nothing else that whole day.Til today there is still no more blood and I don't know what to think.I just now started back taking my vitamins.I'm experiencing cramps in my pelvic region,headaches,I'm always hungry,I always feel like I have to throw up,I feel dizzy sometimes,and I'm always hot.It feels like I'm having hot flashes which can't be right.What do you think it could be?Please write your query here
