Period after D&C?

My clinic won't schedule K's SHG or give us our IVF calendar** until she gets a visit from AF. Tomorrow will be 4 weeks since K had the D&C. So, we are wondering how long it took others to get their first period following a D&C. Also, if you could share what it was like that would be great. I'm not much help in this area because I didn't get a period following my D&C, but that's because I never get one (thanks PCOS!). I appreciate you sharing this with us.

**I should mention that I WILL get a hypothetical calendar from my clinic before the day is over! I've found that persistance and a tad bit of pushiness slathered in butter is helpful in the IF world. I have being sweet, yet demanding down to a science! ;) K and I are both planners and like to know what's in our future, so we just need to know when we might be doing an ER and ET!
