2 months on birth control could I be pregnant?

I started my birth control (Larin 1/20) on 1/7/18 and I’ve been taking them at the exact time none stop and on 3/4/18 I took the generic pill Norethindrone Ethinyl Estradiol that my pharmacy gave me because they were out of Larin and I have also taken them exact time non stop, on 3/20/18 I was having sex with a condom and when he ejaculated his semen spilled out of the condom onto me I’m pretty sure some of it got in. I was on my last week of the generic pill could I be at risk of pregnancy?
