Watery CM after IB?!?!?

[Yoomee]

I'm on day 26 of my very regular 28/29 day cycle and day 14 dpo (I think, not 100% sure when I ovulated). I started spotting on day 21, and spotted on and off until it stopped today. The spotting was orangey pink, then brown, and then a little red. But it was only when I wiped and didn't even require a panty liner. Now I seem to have very watery clear CM. Earlier today I had thought AF arrived because I got a very damp feeling, like a small gush. I went to the bathroom and it was just a lot of watery clear CM. I tested BFN on day 22 and 24. I'm planning on testing again in 3 days if AF doesn't arrive.

Has anyone else experienced this before getting their BFP?!? I'm starting to wonder if my hormones are out of whack and I'm not pregnant, but this is all so out of the ordinary for my cycle!
