Help!!!

So I have a 27% chance of pregnancy today. My boyfriend and I were having sex and the condom slipped off and it was still in me kind of. The opening of the condom was facing downward so the tip part was in my vagina. We then said fuck it and had sex without the condom for 2 to 3 minutes. He re-cleaned himself before putting it back in. He then pulled out and then came. We’re going to go by the pill, but we don’t know how effective it’s going to be or if there’s anything else that we should do.
