pregnancy?

i started taking the mini pill around 3 months ago, and i was on my period for 47 days straight ( i continued to take the pill) i was still sexually active during this time, and my boyfriend would also cum in me. on the 27th my period stopped and he’s now proposed the idea of what if i’m pregnant.

i’m just worried now and i’m going to take a test, i just need to hear a non biased opinion on the situation.

What are my chances of being pregnant?
