I didn't get AF after my D&C (I was 12 weeks with bubs measuring 10) because exactly 6 weeks later I got a BFP after having had very suspicious symptoms... We DTD once. My OB suspected I O'ed 4 weeks after the D&C and ultrasounds backed that up.
At 6 weeks post procedure, I was 4 weeks UTD.

It was hard. Grieving for my loss, being excited for the new bubs and stressing it was going to end the same way... But 9 mths later I gave birth to the most amazing baby girl... I wouldn't have changed any of it even though it was a rollercoaster...
