Okay soo ive been on cazett (how it spelt) bith control for as long as i can remeber. Im 21 and me and bf dnt use any other contreseption. Ive been longing to be pregnant for a while but know its a joint decsion and respect that my bf isnt ready. Im very good a taking my pill and almost never forget to take it, however quite often take it later then i should. Now ive never had regular periods soo dnt know if im coming or going. Sometimes i can go months with out, and then have a super heavyone, other times can have one a month. However ove last month and half ive had serval 3 day periods which ive never had before all being quite light. Its been on a week off 3 on week off order. Could this be a result of me being pregnant? Ive had alot of headaches recently, and gone through moods of eating loads and not eating anything. What are the possibilties?
