could i be pregnant?

me and my boyfriend have had sex. it was unprotected for around a minute then he put a condom on when we decided we were going the whole way. he came earlier in the day but apparently had “the hardest piss of his life” beforehand 😂 well anyways, my periods supposed to start in two days and i’m only have breast symptoms. what do you guys think. (please don’t shame me for the whole no condom thing i’ve cried about it enough 🤧)
