Question for miscarriage and D&C ladies

Steph • 31 yrs old. After 2 losses I finally have my miracle Maverick. TTC again soon
I had a missed miscarriage at 8 weeks pregnant and had a D&C on Thurdsay May 1st. The OBGYN said it takes 4-6 weeks for AF to come after the D&C. I'm just wondering if this time frame was accurate for those of you who have gone through this. I'm very antsy to get AF so I can TTC again.  Thank you!!!!
