help!! going crazy

Lisa • married, current fur mom, and pregnant ❤

I am on the 28 day cycle birth control pill, two days ago I experienced s pulling/ pinching feeling in my belly button.

today I woke up to a brownish mucous discharge in my undergarments, I'd say a medium amount

what could this mean?

should I stop taking my birth control? also its 6 days til my period, should I test soon?
