Is it possible to get pregnant if he just inserted his penis like an inch to my vagina? he didn't ejaculate inside ms.today is my ovulation day.

Sperm can: be present in the pre-ejaculate, so it is possible but not probable to become pregnant in the scenario you describe.

Always possible: so use plan b within 72 hours if you do not want to get pregnant. And use condoms all the time in the future.

Possible: If he some pre cum which contains viable sperm was discharged

A/w Dr Anyanwu: The depth of insertion is immaterial. Even if he didn't appear to ejaculate within the vagina- pre-ejaculate often contains sperm and semen can be released before one if aware that ejaculation has begun. Use safe SEX 100% of the time if not ready for pregnancy. Take home pregnancy test if period is late.
