Can I get some one on one body girl talk here?

So I'm on birth control and for some I'll have a period for thee days then stop after I just had one a week ago. I've been on the pills since June 20 2016. I won't see my obgyn untill June this year. I get nauseous at random times and ever since I had my ovarian cyet erupt (reason why I'm on the pill bc of irregular periods) Can I get advice. I'm 15 btw so it's really confusing why my body is acting like this
