Hi all! I'm going crazy over here and wanted to know if anyone else has a similar story! 
My husband and I have been TTC for 14 months now. I was diagnosed with endo at age 16 (now 23). I have done the surgery, Lupron, and BC to help but the curse of endo is it always comes back. 
I have a regular 35 day cycle and have since the Lupron wore off last spring (2014). Haven't been on BC since. I also was diagnosed with high grade cervical dysplasia in May and had a cryo freezing of my cervix the same month. I had a normal cycle since then. I ovulated around cycle day 28 I believe and I'm now on cycle day 44. I have had 4 days in a row of BFN and it's starting to take a toll on me. 
I have a mild discomfort/cramping in my pelvic region and I have had a lot of watery, sometimes sticky discharge. I also have noticed the white bumps (Montgomery glands) on my areolas in the past few days  other than that I feel okay. No nausea, no mood swings, no spotting. 
I want to be pregnant so bad but my husband doesn't want to get our hopes up until we know. Anyone else have delayed BFP??
