last week I was on my period, it was normal as it usually is, I then started taking my pill again after the week was over (on Wednesday) on the Saturday I started bleeding again once or twice a day and it was thick and dark, it's now Saturday again and I'm still bleeding but it's got heavier and clotted. I unfortunately had an abortion 3 months ago, but my periods have been fine after. What could be the matter? I'm also feel really sick dizzy and can't eat?
