AITA for not bringing up that my roommate may have walked in on me filming NSFW content?

I (21F) make a little solo NSFW content on the side. Nothing extreme, and I’m careful to do it when my roommate (22F) is out usually when she’s at work or with friends. We’ve always had a good relationship, and I’ve never done anything like this in shared spaces or when she’s around.

The other night, I thought she was out and started filming something in my room. My door was mostly closed, and I had some music playing, but at one point I think I heard the front door open. I froze, turned the camera off, and waited. I checked a minute later and saw her stuff by the door, so I’m pretty sure she came in and may have passed my room while I was filming.

She hasn’t said anything about it and I’m not 100% sure she did hear or see anything but since then she’s been acting super polite and kind of overly friendly. It’s subtle, but it’s not how she normally is, and it’s throwing me off. I’m wondering if she maybe realized what I was doing and is just being awkward about it.

Now I’m stuck wondering if I should bring it up to clear the air, in case she’s uncomfortable but doesn’t know how to say anything. Or should I just let it go and act like nothing happened, since maybe she didn’t notice anything and I’d just make things weird by saying something?

I’m not trying to make the living situation uncomfortable, but I also don’t want to ignore something if she is feeling weird about it.

AITA if I don’t bring it up and just let things go?
