Anovulatory Cycle?

Katie • 💖Married July 2018💖Trying for👶#1💖

Alright, ladies. Here's my chart. I would have SWORN I ovulated at CD 13 and that my period was arriving after I had a dip at CD 27 but all I've gotten was 5 days of brown spotting! This is only my 2nd cycle off the pill so my guess is this anovulatory. Any insights?
