Birth control

Erika

Hi guys so I haven’t taken my pills since Saturday because I ran out and I did have sex on Sunday with no condom I was still on my period but very light. So I didn’t take my pills on Sunday Monday nor today which is Tuesday. Idk I’m scared if I could get pregnant? Is that possible? What should I do? My doctor didn’t call in my new pack in the pharmacy so now I have to wait god knows how long.
