Today is CD 17 and tomorrow glow says my fertile week starts.

I have had an ache in the left side of my back and I had slight cramping the other day that only lasted a few seconds. I also had small globs of ewcm mixed with watery/creamy cm a couple days ago. What could this be? Me and my husband BD the 18th, 19th, 20th, and 25th so far. When I went to the bathroom this morning I had this tanish/pinkish/red color on the toilet paper with a very tiny pin point drop of blood on it. But it hasn't been that color ever since this morning. Now it's just a faded tan color. My cervix is also very high to where I can't even feel where the opening is to tell if it's open or closed. I can barely reach my cervix.
