Should I be worried?

I went to my university to spend the weekend to catch up with my roommate as I moved out of college at the end of first semester due to mental health issues. We are not having a good night got to bars with some of her friends that she recently made and I have a friend there who happens to be a guy and he was one of my favorite people ever. I ended up spending the night with him because my roommate went to go party with a group of people and due to Covid I just didn’t feel safe doing that and so he took me back to his room which happens to be next to my roommates and I fell asleep in his bed. I had my period I would say five days before I went and it’s now been over two weeks and I have yet to have my period but we didn’t do anything I did drink but I had to small cups of a mixed drinks and I don’t get tipsy that easy. My only concern is that it has been almost 2 weeks without my period and I know he wouldn’t do anything to me because even though he may be into me he always asked like hey can I hug you or always ask permission and understands that I do have PTSD with an ex of mine. I just want to know should I be worried because my discharge I think for about for five days ended up being The color of your old period blood but it wasn’t really blood I would have a bit of spotting should I be worried? There was no sex going on at all just cuddling fully clothed are you have bad anxiety so do you stress about this I just want to know if I’m overthinking what I usually do or if I should be worried
