Discharge

I've never really had this issue and it's making me think negative. Last week I got really sick at work. Threw up about 5 times and after that day felt a little nauseous for awhile. Also since that day I've had an odd amount of discharge daily. Also I've been having pains in what seems like my ovaries. My boyfriend and I had unprotected sex 2 weeks ago but im on birth control and take it regularly. I'm still 10 days away from my period but I can't help but to think I might be pregnant. Any ideas or insights? Anything is welcome. Thanks in advance.
