i need help

hi! i’ve been in a relationship for around a year now and have been having protected sex for about the past six months. last night we had quite the altercation. my significant other must’ve gotten the wrong size condom, which i guess, happens. But he came inside me with the condom which he usually doesn’t, then when he went to pull out the condom stayed inside me. such a tmi but i’m not going to waste 50 dollars on planb if i don’t need it. i checked myself afterwards and i was quite dry, i peed, and i checked the condom for any tears. i just don’t have the money to be just dropping a 50
