LIP BRUISE FROM KISSING

Okay so I went over this boys house that I’ve been seeing for a while and I’ve had a boyfriend before so it’s not like I never kissed someone like that ever but he completely bit me I guess and I didn’t even notice. He has way more experience than me too so I don’t get why this happened. I didn’t notice until I was going to my car and felt how it felt numb. And it’s huge and swollen and numb still. I’m so scared for tomorrow because I’m a senior and still have school. What do I do about this ?? I’ve been putting ice on it but noticed no difference. Help pls.
