this is my second month on alesse. last month, my period came on time and lasted for about 5, 6 days. my breasts have been sore for the past couple of weeks and i kno for a fact they've grown. (im 18 and i've always had a small chest..they havent grown too much, but i notice my bra cups are a little fuller) i have got occasional headaches and spotting has now started once again (had it last month for about 1-2weeks)... does this have anything to do with the birth control? or is there a possibilty i may be pregnant? help please
