On the 27th, 7 p.m., my boyfriend and i were fooling around and i was giving him a ha****b while making out. He didnt cum. It was pre-cum. Im sure of that. But only slight. We hugged and i noticed a lil of the precum on my t-shirt. somewhere above the waist. Anyway.. so we were hugging and making out. When i saw the small patch on my shirt. I freaked out and i turned the door knob to open the door. turned another door knob to open the washroom door. washed my shirt patch with water then just touched my panties on the vagina area once to check for something.

you think the precum stayed alive//could have entered or anything because of that one touch? 

im sure i touched my shirt/my bfs shirt once-twice before going in to wash my shirt.

ALSO, my periods were expected on the 25th. this happened on the 25th.My periods are usually delayed 4 days. what should i do? should i wait? or take an ipill?? I have never used them before and am very scared! or should i stay calm because i cant get pregnant with what happened yesterday?
