I need advice

Mercedez

So I’m TTC with a fibroid 😩 for the pass few months I’ve been spotting like 6-7 days before my actual period starts. Doctor put me on birth control to see if we can regulate my cycles. So I started the BC the Sunday after I started spotting. This time I only spotting for like 2 day then never got a period. My husband and I never use condoms so could I be pregnant or do you think the BC stopped my period from coming on
