Pregnancy after withdrawal bleeding?

How likely is it to be pregnant after having my withdrawal bleeding for a week? My boyfriend and I had sex without a condom (he did NOT cum inside of me; I know u can be pregnant from precum but idk) but I have been on sprintec for the last 3 months. I’ve been peeing nonstop for the past day & felt really bloated the past week, and yesterday I’ve had right side pain that has persisted into today. I’m just really nervous PLEASE HELP

I do have an appointment w my Ob/gyn this week but I need something to quell my nerves regardless if it’s good or bad
