My Husband and I have been off of birth control since November 2011, and we have had zero luck conceiving. I'm very frustrated, and I'm looking for answers as to why it's not happening. I have gone to our doctor and have gotten tests done. Everything seems to be working properly. They suspect I have endometriosis, but they do not feel that it's affecting my reproductive area. I'm currently baffled as to what my body is currently doing. My last period was June 21. I supposedly ovulated July 12th, and I was supposed to start my period July 26th. AF still hasn't visited. I took a test at 1 day late..negative..and again today at 1 week late..also negative. I have been very crampy, like I will be starting anytime. My cycle ranges from 26-37 days..so on average my cycle length is approximately 35 days. I know the liklihood of my being pregnant at this point are slim, but is anyone else experiencing this or has anyone not tested positive until further along? Please any advice is welcome. Thanks!
