I'm 18 and on the contraceptive pill not because i have sex but because i get ill and lose to much iron during my period. I have been on iron tablets and other tablets to try to lower how heavy the blood flow is but unfortunately i still got bad period pains. I took the pill correctly all last month, like i usually do, and took my 7 day break and now i'm supposed to have taken 4 pills over the last four days. However i have only taken 2 due to forgetfulness and family problems. 
Today, i found that i was bleeding again and was unsure as to why. It may be just because i've missed taking the pill but i've never been irresponsible like this before. I'm just wondering if it is that or what.
Help would be taken gratefully. 
Thanks.
