Still as confused as ever. Temp is even lower today, but still no sign of af. I check cm internally yesterday and there was a drop of fresh blood, when I checked this morning there was just brownish/greyish stuff (sorry). When I woke up my stomach also started churning and I felt really sick, which is how morning sickness started for me last time. Not sure what to think at the moment, as it seems very unlikely that I could be pregnant, altho theoretically possible.
