Not sure what's going on!!!!!

Dawn
I'm not feeling like myself... I feel like I haven't slept in days and this week with school being out still I've actually got to sleep longer than normal... Anyways... Today I've noticed that I'm feeling nauseous on and off and my period is 11 days away and I would of ovualated on Dec.26... I have a yellowish discharge...doesn't smell or itch or anything like that.. Just wondering what could possibly be going on... Please if you can...thank you...
