I work in a medical setting where I am exposed to iso, take x rays, etc. (Relevant, I promise). AF was due 7/2 this month, has not shown, no signs that she is going to. My nipples hurt like I have never felt before, but no other symptoms. I took a test middle of last week and today, both with FMU, both negative. I am never more than a day or two late. I did not track ovulation this cycle but usually ovulate very late (a week before AF usually). Should I make a doctor appointment at this point, or wait and see given the negative tests? Due to my job I want to know if I am pregnant as early as possible so that I can take measures to stay away from radiation, iso, etc. Thoughts? What are the odds of a late BFP?
