How likely will i get pregnant if i am on my ovulation day, bf wore condom in the wrong direction and flipped it before wearing it fully but had precum on him?

Probably very low chance of conception, but not zero risk. Condoms are excellent in preventing STDs, but not so great for contraception. Over time, pregnancy rate is reduced by 90% in couples who rely on condoms for contraception. You would be wise to start proper contraception (pill, subcutaneous insert, IUD) for 100% effective contraception. Good luck.
