I'm on cycle day 49, probably over 10 BFNs now, but have almost every pregnancy symptom (cramps, nausea, peeing every 20 mins, etc) and starting to think it's all in my head... yesterday I started bleeding very little dark blood. Thinking it was my period I geared up for disappointment. Typically I start with a vengeance and need overnight pads right away but this has been the lightest flow and darkest blood ever... hoping to schedule a blood test but is there even a chance I'm pregnant and it's a breakthrough period? Anyone had similar and been pregnant?
