Period after miscarriage

I am always regular 28 day cycle. Last month I used opks and ovulated in cd 16. I tested at 12 dpo and had a faint line. I was pregnant but lost the baby at 5 weeks. I tracked my ovulation again but ovulated later at cd 19. I am now a day late with a high firm cp and creamy cm. did anyone have a weird period (later) after a miscarriage? I've tested but still bfn but I am also only 11 dpo as I ovulated later this month.
