D&C affecting cycle? So frustrated!

Lauren
I miscarried, had a D&C at 10 weeks on 8/30. My first af after that began 10/19, lasted 5 days like normal. 11/1-11/5 cm was very ew/watery, assumed I was ovulating. Had cramps 11/9. Also cm very creamy 11/9-today. 
AF was expected 11/16 but is a no show. BFN everyday this week. I had a touch of pink when I wiped yesterday but nothing today.
Wtf is the deal? My cycles are usually 28 days like clockwork. How long does it take to regulate again?
I'm testing negative but on cd33 with no sign of af. I'm so frustrated.
