Hi hun, I too have PCOS and had lap&dye/D&C in May. I had three cycles of clomid at arying doses before that but didn't ovulate on it. Anyway the procedure itself is done under general anaesthetic(Ihad never had one and was a bit apprehensive) and is relatively short - about 45 mins. It's usually done as a day procedure. I had bleeding for the cupl days after and it quickly slowed to spotting. I was sore but nothing that nurofen plus couldn't handle although some docs give prescription fro stronger meds depending on pain threshold. My FS found some endometriosis which was removed via D&C during it. I also got some pain in my shoulders as the gas they use to inflate your uterus moves upwards when leaving the body. Your tummy will be swollen and will take a few days to go down.
Now...onto TTC after it. Well firstly you can have sex again as soon as you fell comfortable. Think it was about 10 days for me. I started an injectable cycle about 3 wks after the lap and that resulted in a pregnancy. Unfortunately my little Bean didn't make it but that had nothing to do with having had the lap. Research has found that women tend to be more fertile during the 3 months after a Lap/D&C as the operation gives the uterus a good clearout!
Hope this isn't info overload for you. Any other questions just shout!
