Maybe Pregnant??

Unprotected sex with my husband January 3rd, I take the pill but not always at the same time/hour every day. 
Woke up at 6am to extreme nausea but no vommitting, had some light red/brown spotting and cramping on the 10th of January. Loosing weight because I have food issues (willing to seek help if I am pregnant) but not as fast as I used to and increased breast tenderness and AF due in 6-9 days. 
17 days dpo before unprotected sex and 17 dpo  since unprotected sex. I know I said I take birth control but my Clue app still includes fertility and pms times despite birth control pill so I included that information anyway. 
Update; not ttc, people always ask for more info and I can't comment on anonymous.
