COULD I BE PREGNANT?

So I’m on bc and I normally start the pill on Friday. Then I had a break for a month and started again this month, on Saturday.

I had sex a few times with my boyf and we always used a condom and I checked the condom always and it was not broken. Still I’m afraid that something could enter my body when we were together messing around.

So, usually I have my period 3 days after finishing the bc, but this month it’s been 4 days and I only had a light brown spotting.

Could I be pregnant?
