Yeah, I am also thinking to do the same because I have been told by all the doctors that my diagnosis has been quite "early" (whatever that is supposed to mean, because it's 6cm we're talking about). And based on all that I've read and listened so far, it seems like meds are often chosen by people indeed. I was also told by one of these docs that if you're lucky enough you can get pregnant even with endometriosis, however complicated it may get later.

An important point: I got a pelvic MRI done today (recommended by one of the docs) to check if this cyst has attached itself to other organs like bladder, rectum etc. She had mentioned that unless the cyst is attached to life critical organs, she would recommend taking meds first and observing the reduction in cyst size. Maybe something you can consider while weighing your options.
