If I had a potential risk (guy touched my vagina through my underwear with his fingers, and I don’t know if there is precum on his fingers, there was no ejaculation/cum) 2 days before my period came, does it mean that there is zero chance I got pregnant due to that incident? The incident happened on 8 August, my period came on 11 August. Does it mean I had zero chance of being pregnant due to this incident?
I know that sperms can live in the cervix for up to 5 days and I am worried about that. Is it possible that any sperm can wait there while I have my period for the next 3 days and fertilise the egg for the next cycle when my period is finish since my period is only lasts for 3 days? Meaning can it be that I had my period this month, but I may actually be pregnant next month due to that incident? My cycle is usually 39 to 43 days long.
