What do periods look like with anovulatory cycles?

V • After 14 months of struggle, had baby girl in 10/2015! So blessed...
Hi all, I'm on cd 60 and assuming I didn't ovulate this cycle. (Bfn with FMU and blood hcg) I've had 2 days of dark brown spotting with no AF and bbt is rises for 2-3 days then falls over and over again. For those of you who have had anovulatory cycles, what was your period like? Thanks!
