I did have increased cramping immediately following my DS, but only because my period actually started. Had not had one for 20 years due to my weight and it has been like clockwork since about 8-days post op.
Beyond that, I can't offer much except, I did begin in about my 2nd or 3rd year post-op to experience stabbing pain regularly about 4-5 days before my flow starts. My GYN ordered a pelvic ultrasound and discovered I have a fibroid along the back wall. You may want to look into that as it's my understanding that depening upon where the fibroid is, it can't always be seen laproscopically. I'd advise getting a pelvic ultrasound.
Hope you are able to get it resolved soon.
