I got pregnant after my 1st miscarriage. Granted it was after the first period, though. My daughter is now 20 months old and happens to be taking an afternoon nap as I type this. Good luck to you!
If you had your scan on Monday and they said you were about to O. That would mean you probably O'd Tuesday at the latest? The egg will only stay viable for 12 hours (from what I have read). So if you bd'd this morning, Friday, I would say it's highly unlikely for the egg to still be there and viable. But unfortunately, no matter how much research we do, our bodies will do what they want. So, there is still that possibility.
I have talked with so many ladies that got pregnant within the first month of having a m/c and had a healthy pregnancy and baby. most of them had a natural m/c and no d&c though. did you have a d&c?
try not to stress about it. it is possible to have a healthy pregnancy this soon after a m/c. let us know what heppens
