It's really difficult to say what could be going on because you are definitely very irregular, which could be a sign of a fertility problem, which could make it harder to conceive (did the doctor check any of that out?). Obviously the only true way to prevent pregnancy is not having sex at all- which I'm sure you know that. So if you do have unprotected sex while on the birth control/ovulation control (is that what OC stands for?) you can still get pregnant. It will probably regulate you much better.
I would think that you're not pregnant. You could always re-test now. If it is still negative I highly doubt you are pregnant because it's been more than two weeks since the last time you had sex (March 13th). If it is positive, discontinue taking your OC and contact your doctor. I know many mommas who finished college and still had their babies. So even if it isn't ideal you can still do it!
Let us know if it ends up being positive or negative.
