HUGS Yo
Its hard not knowing if everything is working in there!
Maybe it was more than a couple of days for ovulation? Some people have a really long luteal phase and some have shorter phases - it averages at 14 days maybe you're just running a bit longer.
While there is a possibility of pregnancy with withdrawl - its pretty unlikely, but if you are worried you could try testing.
I didn't have a DnC but my cycle post MC was 6 wks long - my dr said anything from 0 -4 wks was a normal delay for things to start working.
HUGS - I'm sure it won't be long.
