Cervical Mucus

TMI- my cervical mucus is dry and looks like cottage chese I am not pregnant ( I know of this because I had a blood test done)  I have not had a period in 2 months now. (Still running test. When I rub it on my fingers it is like dry flour that you are rubbing off your hands. By chance is my period near? I had swollen nipples  a couple of days that is gone now. And slight grumble in my pelvic normally when my pelvic does this I know my period is coming.
