is it possible ?

hi y’all. so i’m on a combination birth control pill. haven’t missed a pill ever. my last period ended 1/16. my bf never finishes in me. however, i am not feeling so well - nauseated, stuffy nose, sinus pain, and fatigue.

i know those can also be symptoms of pregnancy but if i haven’t missed a pill before my period and up until now, there’s no chance i could really be pregnant right ?
