To Slide or Not to Slide in the DM’s

So I recently matched with someone on Bumble and it seemed like we have a lot in common. Unfortunately the match expired though and I never got the chance to talk to her. Fast forward about 2 days later and the same match popped up on my instagram suggested feed. I thought that it'd probably be odd already to request to follow her, but I was like wth I've got nothing to lose and she ended up following me back too. Now I'm curious, should I try and message her? I figured if she wanted nothing with me at all she would've just not followed me back, but I know that the follow isn't an invitation to reach out also haha. So I'd just like to get some feedback if I should message her? And if so, do I mention that we matched at all or just act like it didn't happen? TIA
