Left with hickies that make it painful to walk or move

I (18f) had a hookup with a girl (17f) after knowing her for only a few days. She asked me out on a date, we fooled around, and it went further than I expected. I consented, but I don’t think I really wanted it, as now it feels like my first time was wasted on someone I hardly know or like.

Anyways Throughout that span of roughly 6 or 7 hours, I ended up with a ton of hickies. There’s these two clusters(?) of them on both my inner thighs that are extremely painful and swollen, and they’re sort of starting to get Black-ish and spread.

It hurts to walk or move too much, and I have to walk graduation tomorrow morning, so I’m scared I’ll mess up due to the pain.

Is that level of bruising/pain normal for hickies? It really hurt in the moment, but I didn’t expect so much swelling and stuff
