HELP I’M PANACKING

my boyfriend just came during sex and obviously it was protected but I saw when he pulled out there wasn’t much cum inside , and I looked closer and the condom had ripped i started freaking out and crying because I’m traditional so Ive never been on the pill and i’ve taken emergency contraception before once and it messed my hormones up and made me gain weight dramatically and I’m just scared because even the plan B has about a 95% of working . I keep crying but my boyfriend is being supportive and he said he’d go get it for me so I guess that’s a positive .
