Any other ladies with endo all of a sudden get an irregular cycle? Was 8 days late last 2 cycles and now I'm on cycle day 44 with no AF. My cycle is usually 35 days. I've been TTC since June of 2014 and that whole time my cycle was regular until 3 months ago. I controlled my cycle with BC pills until I started TTC but I haven't been on them since. This is so frustrating.
