What is this?

What could this be? I’ve never had this before— it almost looks like it could be after AF is over and you get the older blood, but still not quite- plus she hasn’t shown up yet and isn’t due for 2-3 days. It’s a bit like watery, up top almost like discharge I’d want to say. I’m kind of worried if I’m being honest lol I’ve not had this before, me and my SO did have intercourse last night however and we are TTC, it that helps but I’m thinking we’re out for this cycle.
