lightning crotch and not pregnant (yet)

Okay so I finanlly found some articles relating lightning crotch or round ligament pain to PCOS although there isn't a whole lot of documentation to support it I am fairly confident it is related. Ever since I stopped BC the day after I get a positive ovulation test I get severe lightning crotch for hours on end I am on severe pain, I can hardly move and it almost feels like a contraction or the worst period cramps of your life. I found in my search this is also possibly related to Endometriosis, however there was no evidence when I was checked that I have that only confirmed PCOS. Any way. Does any one know of a way to relieve this pain? Or prevent it from happening all together it keeps me from sleeping and forget about work. We are trying for a baby or I would go back to BC it's the only time I remember not suffering this pain.
