I can only speak of my experience with a d&c - not the lap. I had a d&c last year after a missed m/c around 8 weeks. It took 6 weeks for AF to return - came back as per normal.

2 months ago I had a 2nd d&c b/c of a m/c at 5 weeks but my hcg kept rising thus they thought I had some retained material (as they say). Even though it was even earlier in the pregnancy than last time, I just got my period this morning 8 weeks to the day from my d&c. The wait was horrible...and this AF is very heavy and painful (not normal for me) but at least it's here.

All I can say is everyone is different. And even with the same person, the experience can differ. I did push for some tests and they were able to do BTs to see if ovulation had occurred or if it had been delayed. My first BT at about 6 weeks post d&c showed that I hadn't ovulated...and then my BT at 7 weeks showed I had just ovulated very recently (they tested a number of hormone levels each time) and my dr predicted I'd have my period by the end of this week...and she was spot on. If you are concerned, I suggest asking for some sporadic BTs to track ovulation. I was definitely pushy about getting some answers...sitting and waiting, well that just didn't sit well with me.

Good luck!!
