Jumping in here with a few thoughts/tips.
Ladies please push for EXCISION surgery rather than ablation for endo. Ablation only burns off the top layer of endometriosis - excision cuts it out like a root and significantly reduces the chances of reoccurrence (ie. endo growing back). Remember endometriosis can never be cured, only treated. On the other hand, a hysterectomy is the only cure for adenomyosis (since it only affects the uterus) but a lot of people have both conditions. Endometriosis can still grow back after a hysterectomy.
Nancy's Nook is a great resource for finding proper endometriosis specialists (the majority of OBGYNs aren't specially trained in endometriosis surgery):
This is an endometriosis learning library. It contains information collected and shared over many years. We have now compiled these resources and present them for you as a living library of information that will continue to grow. It is up to you what you do with that information.

The FB group "The Endo Space" also has a lot of useful info.
I also love @mypelvicpain @reythewarrior on Instagram
More often than not, ultrasounds and MRIs are a waste of time unless you have deep infiltrating endometriosis. The only way to be formally diagnosed is via laparoscopy so please don't allow GPs to fob you off. Push for surgery at least so you can have a proper diagnosis. If they don't find anything it's likely because they're not an endo specialist and don't know what to properly look for.
Pelvic floor therapy also helps as a treatment (not a cure), Your pelvis and abdomen and surrounding muscles are so seized up from being in constant pain. PT helps to loosen these muscles and helps your pelvis function better. When I first started going I was basically seized up from my ribcage to my knees without even realizing.
It breaks my heart seeing so many women in pain and getting no quality care from their GPs and even GYNs. It's outrageous how under researched and underfunded endometriosis and adenomyosis is. I'm in the US and travel 3 hours to see a specialist surgeon. We are failing so many women with this awful disease.
