Precum=pregnant

tris

Had sex with my boyfriend. Before he even put it in a little bit of precum cameout. Right after that he put a condom on. After awhile. The condom slipped off inside of me while he was pulling out. But he did not cum yet. He quickly took the condom out of me and put a new one on. This was a day after my ovulation ended.. could I be pregnant? I am also taking birth control and was still on the first week of the sugar pills
