I started the 28 day Sprintec birth control on Sunday (Jan. 25) and had sex last night Tuesday (Jan. 27). So in total, I had been on the Pill a whole 3 days. My partner didn't use a condom. He didn't come inside me. He also didn't get pre-jac inside me. Should I be worried at all?

(also I had/have been taking the medicine at the same time each of the three days)
