morning sickness??

So you guys I am very confused with what's going on with my body. Every morning since Tuesday I have woke up nauseous and I usually throw up and go about my day. I haven't had much of an appetite either. 
I had my period Tuesday night it was very heavy with clots like I'd never had before for one day - then it continued like a very light period. 
Soo I am still nauseous today (Saturday) and confused as hell. 
Btw: went to dr Thursday for a sinus infection and asked the dr about this but I didn't get any answers and I'm starting to think she's a dumbass as she asked me since I was allergic to penicillin If I could take ammoxicillin instead?!
