Am i pregnant? im a little worried right now,?

i think it is a possiblility that i may be pregnant. i recently stared birth control and my boyfriend blew in me for the first time but not until after i had gone through a whole 21 day pack. i am over a week late for my period and thats not completely normal. for the most part i started birth control to regulate my period but having a boyfriend we will obv take advantage of the other effects it has. although my period was irregular it was still not normal for it to be way over a week late. ive got hard core depression and vaginal discharge has increased alot (awkward..) ive had many headaches and lower pains as well as feeling dizzy often. the birth control pill i am currently taking is CyEstra 35. (My doctor put me on the "acne preventative" BC because i had ONE pimple, and i only had a pimple cause ive been stressed over school plus at the time i had my period) so i was just wondering if anyone had anythoughts on if you think it is possible i am pregnant or not. if i had just missed my period and not had these pains and extra discharge i wouldnt have been so conserned. i have been on the pill now through almost 2 packs of 21 pills. thoughts?? :|
