I am on my 3rd day in for my fertility window. Today I have had so much cervical mucus to the point where if I stand up without pants on it'll run down my leg and I mean a lot. I'm having really bad lower back pain and pain right above my pelvis area, haven't felt good today nothing sounds good to eat. Is this cause I'm ovulating today or what? If never had it be this bad before. Please help lol.
