Im on my 3rd day of my period i had unprotected sex but only pre ejaculation went inside im 32 day cycle what are my chances? thank you !

It Is Possible: Yes, you could get pregnant form this. Any unpotected sex can result in pregnancy and there are semen present in "pre ejaculate".

Very low: Having sex during the period is unlikely to result in a conception unless your periods are regular and come about every 21 days. Then the chance of conceiving is increased even when having sex during your period.
