Bleeding- TMI

I took a FRER Friday and got a vvvfl. Took another this morning darker but still faint line. I have symptoms. Exhausted. Not feeling well. Peeing all the time. This morning I let the dogs out and my underwear felt wet. I went to the bathroom and lots of blood. It seems to be watery mixed with cervical mucus but still going. I called the birth center and it's basically a waiting game. Any thoughts? Is this AF or what's going on? It certainly doesn't look or seem like AF. Hard to see the consistency in photo but it's very liquidy.
