Hello, I Am Stressing Out Because I'm Not Sure If

Hello, i am stressing out because I'm not sure if my period is delayed or if I'm pregnant, my boyfriend was jacking off and got cum on his hand then accidentally touched my vagina, but we quickly wiped it all off and I went to the bathroom and peed and wiped extremely good. I am stressed out right now and have been worrisome about my grandmother, and I have been drinking a lot of water and have been active lately, and I know those can also delay your period, my period usually is somewhat on time but I don't remember when my period was last month.
