Heidi,I have many of the symtpoms you describe, but some of them are not caused my endometriosis. In my case, the infrequent periods and hot flashes were caused by polycystic ovarian syndrome (PCOS). Since I started taking the birth control pill, which I had to take for the PCOS, many of those symptoms have disappeared.I see you mentioned you don't want to take the pill, so maybe that's not an option for you. It's good that you're having the problem looked into. Hopefully, you will find something to help you out.
