Im 24+ days from my last period and im an irregular.my boyfriend urinated in the morning and we did it like in the afternoon. We didn't really have sex but he places his penis on the opening and tried to put it in but it didn't fit and i became scared. I was very wet that day, i was having a white discharge. Could i possibly become pregnant from just pre cm? He didn't put it all the way and just was therefor like a minute trying to put it in and possibly made contact with precm. Thanks
