Does my symptyoms and bbt indicate i am pregnant

Patient: I took i pill around 3 january. My periods got over on dec 25 . after the emergency contraceptive got periods again on 9 jan. Then next month 9 feb. And had intercourse two days after end of period on 14 and 15 feb. After 4-5 days noticed fuller boobs,food aversion and still having headaches. It is a sudden change. Due to irregular periods i am not able to find when i ovulated. Also my bbt was high the whole week after period. Are there chances that i m pregnant or is it just ovulation phase?

Symptoms: Fuller boobs, food aversion and headaches
