okay so long story short I went to my friends house there was this guy that I met there we got drunk and things got heated and he started fingering me but the thing was I totally forgot my period was barely done the day before

So after everything happened I went to the restroom and I see blood on my panties ... when I seen this I called and Uber && left idk if he saw blood on his hand or something but I’m embarrassed af and idk what to do should I apologize?? I haven’t talked to him since.
