23 days late, no AF, neg blood test.

What else could it be? I've come to terms that I'm probably not pregnant, but I have pcos and a history of very late only positive through ultrasound pregnancies in my family, so my husband is still convinced I need an ultrasound. My last period was March 6, I've got symptoms galore, and not nearly what I'm used to as far as cyst pain, but light crampin g for sure.

My whole stomach is rock hard, and my uterus (I believe ) is starting to protrude.... I know that I have regular bowels, which is wh at the doctor shoved me out of her office without verifying but assumes is my problem.

No sign of spottin g at all, no AF like pains, just cramping, and I've had a consistently 29 day cycle for over a year now other than a chemical pregnancy confirmed in August.

What the heck else could be going on, and what test is next? I just want to get back to my normal cycle and not feel like I've got a basketball lugging around in my tummy!
