AF was supposed to be here last Friday, the 17. Never showed her ugly head. Usually she shows up a day early, like every time! 3 weeks ago I experienced 5 days of diarrhea until early afternoon, afternoon nausea, tender nipples, lower back pain, cramping, and extreme tiredness. The last 2 weeks I have felt great, other then having insomnia. I have done 5 HPT and all have been BFN. The DH and I decided to BD last night since AF still hadn't showed and he mentioned that I felt a little different? Which is weird. I'm not sure what to think or do. We have been TTC for 2 years....
