I've been having the same problem of late... I'm still waiting for AF back after my youngest's birth (15 months ago) and I also have PCOS.... I know every month around my old ov and AF times I'd get pain, but for the past 5 weeks I've had it constant. I thought I could have been UTD with other symptoms, but 3 tests later and all negative I doubt I am!

I have no idea what it is caused from, or why it's all month long, but I can certainly empathise! *hugs(
