I so scared

the 28 of the September was the last day of my period me and by bf decided to take a shower toghtwr and things escalated . But basically I was standing up on the sides of the bathtub/ shower and we were making out. He was fingering me and I was diving hung a hand job, I was elevated and all of the sudden he came. He said his fingers were still in my vagina when he came and I think that if any sperm even went close to my vagina it could’ve not gone in because his fingers were still in there and like technically his hand was covering my vagina. After I realized I had cum on my hand he took out his fingers and moved his hand I grabbed the soap and washed my hands and then rinsed them. And the day before he fingered me but he said there was no sperm on his hand

UPDATE

Today I am 9 days away from my next period and my bf felt my boobs and their are really hard I’m literally so worried pls help what does this mean. Also they have been really sensible for a while and I’m really really worried

Why are my boobs hard
