Period after D&C?

Shaina • Momma to an angel baby (1/15) and my sweet 3 year old boy (8/16)!
I found out I had a missed miscarriage on Monday, January 26th. I should have been 11w1d but my sweet girl was only measuring 9w (I'm high risk and had just seen her at my 9w appointment and everything was perfect). I had a D&C the next day, Tuesday, January 27th. How long did it take for you to get your first period? I still haven't gotten my first period. OB says we can try again after first menstrual cycle and my husband and I are so anxious to try again! This was our first baby..
