I was on a similar pill to this one, and it was all new to me..so i also freaked out!
I bled when i shouldn't be at all.. i had my period, then two weeks later I got it again! and it went on for ages.
Started to freak out, and then talked to my mates n one said that it just isn't strong enough for me...
Also sometimes I forgot to take it, so i would just wait til the next day and take the next one.. But apparently im not suposed to do that as i need one every day no matter when.
Anyway, i got off that pill straight away, i got back to my regular pattern again, let my body get back to normal cuz it was completely screwed up!! and I went back to the doctor and got another prescription. i havent used it yet but im hoping it will work
