I have always had period problems ever since I started having my period, my hormones are all over the place and I think I got really messed up by taking the after pill.

Basically after taking it i didn't have my period for 3 weeks and suddenly my period came very heavily (I used a tampon and a large pad every hour) and I am really scared! It's been going on for 5 days now and I am really starting to worry.  I feel so ill, every time I stand up I feel like fainting.
