Any advice?

Lee • Mommy to 3 year old girl! Baby #2 joining us March 2016!!!
I've been off the pill since March and started TTC in July. I was having fairly regular periods up until the first cycle we were TTC. Since then I had a 40 day cycle and I'm currently on CD40 of my next cycle (with spotting on CD32 which isn't typical for me). I know I'm not pregnant (I got a neg test this AM). Has anyone else had crazy cycles this long after stopping the pill? It's a tease because I get hopeful each month!
