Am I overreacting as to why my husband’s coworker is viewing my profile so much?

I’m going to try to write this out without sounding completely insecure and ridiculous.

My husband has a female coworker. She’s married. I’ve met her in person twice. The first time, she didn’t speak to me at all when we were introduced, and the second time she said maybe one sentence to me. It was civil, small talk. “Don’t you wish you had that much energy?” while my oldest was running wild in the park.
But then she started following me on TikTok (mine’s set to private) and it notifies me every time someone views my profile. In the last year or so, she has viewed my profile probably 15-20 times, which may not seem like a whole lot, but it’s weird because we’re not friends by any means. And it’s not like I’m particularly entertaining on there or anything. It’s just a bunch of reposts and the occasional video of our kids every couple of months.

Husband just shrugs, “she’s creeping.”
Creeping why? My first thought is she’s curious about (or maybe interested in) my husband and wants to see what I’m like, what our family dynamic is, how he is with the boys, etc.
My husband thinks it’s harmless, but I’m side eyeing the shit out of her now because it seems off to me.
When I was still in the dating scene, and being the jealous and nosy type, I would peruse the MySpace profiles (showing my age here!) of a boyfriend’s ex or a crush’s girlfriend, I guess to size them up. I feel like that’s what’s going on here. AIO or does this feel shady to anyone else?
