Will I get pregnant?

Just a little paranoid. So I’ve been on combination birth control pills for 10 months now. Haven’t missed a day or anything but I’m just paranoid. I hope someone can give me advice.

I start my pill pack every monday and usually get my period every last saturday of the month which falls on the 6th day of my sugar pills and lasts 3-5 days. My last period was on January 2 to 7.

I started my pill pack on January 4 and I had sex on January 9 which makes it the 5th day since I started my pill pack for the month of January.

But I looked at the calendar here after we had sex and it says I was going to ovulate on January 10 to 16 which was the next day right after I had sex. We didn’t use condoms and he came inside me. I didn’t get any plan b as well because I’m already on the pill.

Should I have gotten plan b?

Is there any chance I’ll get pregnant even if I’ve been on birth control pills for 10 months?

Will I get pregnant because I had sex the day before my ovulation week while on birth control pills?
