A little help please

Confused a little...maybe a little tmi

So my obgyn wanted me to take a low dose birth control for 6 months and lose a little bit more weight. ..well I took the pills for 2 days and every morning after I would have a sever anxiety attack all day...I baby danced with my fiance on my most fertile day in November which was the 17th my entire in law family swears im pregnant. I had a pretty normal 6 day period but its normally a little heavier and I pass some clots well this period I didnt I took a hpt on Nov 23 and it was neg which I expected it to be but is there still a good possibility im actually pregnant and just had that one last period ? I have some pregnancy symptoms ive been sick for like 3 weeks with a cold im light headed and dizzy I have major headaches everyday now and im nauseous, and according to my mother in law my areola is darker and also bigger im bitchy, moody, and tired a lot more then normal. Ground beef doesn't taste the same anymore and I used to like eating Turkey sandwitchs and now I can't eat it without wanting to throw up. Ive also had very bad heartburn lately. A little advise and comments would help I dont exactly have other people that can help with my dilemma.
