Anybody had a Laparoscopy for Endometriosis

I’m having this surgery on Friday. My reproductive endocrinologist is performing a laparoscopy to determine if I have endometriosis. I have had a series of procedures performed in which the doctor decided something is blocking my left tube as well as pain and unusual spotting. Has anybody had this done before? What can I expect for downtime? Did this result on you getting pregnant? How long did it take.
