I have had pretty regular cycles since coming of bc in the spring. My husband and I have been ttc for about 2 months now. My last AF was heavy and had horrible cramping. (Not normal for me). This month I have very mild cramps but they don't last long...more like poking. I feel like I have to pee every 10 minutes or so, been having vivid dreams, dizzy (but have had vertigo in the past so I don't really pay much attention to that). I took a test on Monday (1 day late) and got a BFN. Could it be a false neg? Or is it all in my head?
