Hi. I'm A 21 Year Old Girl. I Have Been

Hi. I'm a 21 year old girl. I have been feeling polish since yesterday after eating pizza.i had not slept for 24 bourse when I had the pizza. During those 24 hours, I had coffee, lemon water, pizza and a banana. I also took a crocin and a disprin back to back because of headache due to lack of sleep. I am currently using progesterone cream due to hormone imbalance. My period date is in 2 to 4 days. I had intercourse about 3 days back. Before that I had intercourse a week back. I have sore breasts, bloating and nausea. This morning I am feeling sick as well, lemon water is good. Even the thought of food is making me sick. I slept for 12 hours. Am I pregnant? Or am I about to get my period? Or do I have food poisoning?
