Visanne trial without formal diagnosis. Does it make sense?

Hi. I have been suffering with severe bladder control loss, pain in bladder upon even slight filling, painful sex, painful periods and general fatigue. I was diagnosed with Interstitial Cystitis initially and gynaecologists also suspect Endometriosis.

However, my urogynaecologist has put me on Visanne as a trial and she says that a laproscopy is unnecessary and considered a last resort according to international guidelines on diagnosing Endometriosis.

I feel like my symptoms are driving me crazy and I’m not sure if this was the right approach? So if I react well to this medicine, she’d diagnose me with Endo and if I don’t respond well to it (most of my day to day symptoms are extremely bladder related) then she’d disregard this suspicion.

Please tell me if this approach makes sense? I have two kids so fertility isn’t a concern. But I’m not really happy putting myself into chemical menopause without a clear diagnosis.
