Scared.

Hello, I am on CD 24 and yesterday I had experience a small wave of what would be a cramp then that was it, I took a pregnancy test and it came out negative now today I went to the restroom and there was blood and what looked to be like clear fluid mixed with it and as I keep wiping it’s not pink but it isn’t brown it’s a mixture of both. I’m freaking out, can someone please help me understand what’s going on?
