Could I be pregnant??

So I had sex on November 22nd I believe maybe it’s to soon not sure. But I’m not sure I actually had sex while I was ovulating and Fertile. My stomach is now looking bloated as hell and I just been feeling and looking weird my face is getting a little fat. I been hungry as hell and idk I just don’t look right and I been feeling weird. I never been pregnant I hear you do go through bloating this lotion I used never bothered me before now I can’t take the smell. I was smoking a cigarette and it exactly made me feel sick. Can someone tell me what they think.
