birth control and pregnancy

I feel like this is honestly a really dumb set of questions, but whatever.

I had unprotected sex during my placebo week of my pills (period week). I take my pill regularly and everything, but anyways, I’m anxiety ridden and paranoid that I may still fall pregnant.

Should I stop taking my pills until it’s been long enough that a pregnancy test would be accurate? Or should I keep taking them?

Mentally, I don’t know if I could handle getting an abortion, so if it ends up that I am pregnant, would me continuing my pills have negative effects?
