sallyk - I just wanted to answer 2 of your questions

I had a D&C after a missed m/c at 12 weeks and AF took 6 weeks to return. Also your q about workout intensity, I don't workout at all LOL I prefer a light walk, but after my embryo transfer that resulted in this pregnancy I asked my FS is there was anything I should avoid doing and he said he wouldn't recommend going out and doing an intensive aerobics class or anything that lifts your body temp excessively. So if it's an intensive class, I would probably drop it down a notch. HTH and good luck

to all you other lovely ladies, hope you're having a nice weekend!
