I had a d & c after a blighted ovum (when the embryo doesn't develop at all and all you're left with is the egg sac and developing placenta). I waited until I had a proper period, which was about six weeks after I think. The next cycle was a bit off (much shorter than normal) and I didn't conceive. The cycle after that I fell pregnant and went on to have a healthy DD (now 11 months). Good luck and hope all goes well.
I had a D&C after a mmc, it then took me 11 cycles to conceive again. My periods were a lot lighter at first, so I don’t know if my lining was a bit thin and if that contributed to the slightly longer time ttc, but all turned out well in the end. Good luck!
Thanks for your responses! Good luck where did the back boobs. I feel like this is the year I try everything I can because I don't know if I will have the emotional energy to keep trying for years. I am pretty sure I have some kind of scarring or endometriosis. Hopefully this will give me a chance to start ttc with a clean slate.
