Hello and Welcome to the Pain Management Forum. I am sorry to hear about your pain.
Have you consulted your PCP? Have you had a clinical evaluation, tests or the like done? Pelvic, lower abd pain can have so many sources that it's difficult to guess. I encourage you to consult your physician and the sooner the better.
We also have a Forum for undiagnosed symptoms that will probably be better suited for your question. Please know that you are always welcome at the PM Forum but another forum may offer you additional suggestions/help. Here's the link:

I hope you will let us know how your appointment turns out. We'll look forward to your updates.
Take Care,
~Tuck
