Not ovulating?

Christie • Hi Glow family! I`m a happily married lady with a son. TTC #2 I`m a festival goer and lover of music.
I'm fearing I may not have ovulated this month... I'm using CBFM and have 9 days of high fertility but no peak... AF is due in 6 days.... Just seams abut strange. Do u think I can still ovulate? Should I try another month of CBFM and if I get the same thing call my dr. We have been trying for 5 months.
