I have also been wondering about this, my MC was confirmed on the 3rd, and I was trying to figure out when I ovulate this month, based on my last actual period and/or the MC bleeding. I've managed to create a window between the 5th and 11th of this month, so me and my OH are BDing every day until then, and regularly after that too... keeping our fingers crossed...
I hope we can get to where we were and carry on this time, we were so gutted that we lost our little bean and I'll never forget what could have been... but we are both just so glad we were able to conceive in the first place since we are both young and it took us 7 months.
Hope you're all okay and I'm sorry for your losses.
My doctor said to wait until my next AF to try again, but me and my OH can't see any harm in trying now, since I've heard so often that you are more fertile after a MC! My OH's sister had 3 MC's and after 2 of those she conceived the next month... fingers crossed for us all, I can't stand waiting again.
