Matched with a girl on a dating app, spoke to her everyday, she hasn't replied for over 24 hours

[WheelWorks]

I matched with a girl on a dating app last week, she seemed really interested in me and gave me her number so we started talking on WhatsApp everyday. She was being really nice and we were getting on well but I haven't heard back from her for over a day now, my last message to her on WhatsApp is coming up with 1 tick only which means it hasn't been delivered. I know she hasn't blocked me on WhatsApp because I can still see her profile status and picture. However, this morning I noticed that her dating profile is no longer there.

What could this mean and am I overthinking it?

She's met someone else

Give it a few more days then send another message
her phone may have broken, she may have lost it etc
don’t panic

Met someone else or just decided to take a break from the site maybe. You've only known her a week, and you have her WhatsApp, she will get back to you if she's interested.

There isn't anything to think about.

Classic ghosting im afraid. Standard for dating apps
