I first time had kising with my boyfriend and in excitement we both removed our clothes. We did not had intercourse but might be accidentely his cock liquid( not sperms) must have got touch my vagina.
Hence for precaution I took oral pills within 24 hours but as my periods date was on 5th June but till today I did not had my bleedings.
Does Pills delayed my periods or I am conceived?

IF he is not a rare case where there is sperm in pre-ejaculate fluid and IF he did not ejaculate at any other time, no, you cannot be pregnant. I don't know what "... must have touch my vagina" means. You don't know?

If no sperm was released (and I am not 100% certain that either one of you would recognize the difference between pre ejaculate and ejaculation/leaking sperm) you cannot be pregnant.
