Help, did I overshare?

Have been having painful period all day so I’ve been walking around the office since it felt uncomfortable to sit down.

Instead of having my lunch break, I was just pacing back and forth with in the seating area where my colleague was sitting.

I could tell by his facial expressions that he was wondering why I was pacing around so I said “sorry if I’m being annoying by walking around, I’m just in pain”

When he asked what was wrong

“ I said stomach pains” I eventually told him it was cramps when he asked what sort of stomach pain it was. After I said that, he looked visibly uncomfortable and went back to reading his paper.

I’m an extreme overthinking and now I can’t help feeling like I overshared and embarrassed myself. Especially because i barely talk to any of my colleagues.
