Laparoscopy & Hystoscopy for Endo?

Hey ladies, I'm finalllllllly after 2 years of excruciating periods and ovulation and not being able to have sex, going to get the procedures I need in hopes to be healthy and normal again! I have possible Endometriosis/IBS/Spastic Colon and have had a gallbladder removal so I have many stomach issues and all combined they SUCK. My question is has anyone had the lap. or hystoscopy? They are saying they're going to do a D & C which I've never had, I've never been pregnant (so I've never MC) but they say it's just to go in and clean everything out and see if there are polyps, cyst, whatever... I am just really nervous about it all, and am hoping this helps me with pain, sex and conceiving. just looking for some personal stories maybe... thank you :)
