cd46 and BFN, any advice??? help!

Help!!! I'm on cycle day 46 with no period in sight and a slew of BFNs. 
I'm ttc #2, my dd was born March 2015, breastfeed for just over a year- at which point I started using glow. 
First period in March 
April 53 days
May 33d
June 33d
July 31d
Aug 32d
And now Sept/oct 46 days and counting. Has anyone had this. Did you call dr and could they do anything? I have no pain or cramps or anything..!
