i'm quite interested to see how this pans out for you, notquitesure - i'm in a similar position myself at the moment and don't feel like i'm properly having AF either. It was a day late for starters, and now in its second day but so far has just been a bit of watery blood (eurgh, sorry!) - it'd usually be heavy and red at this point, but this has just veered between pink and brown. I've been wearing pads in case it suddenly becomes heavy, but liners would've been fine as it's been so light. I don't have any heavy AF cramps, which I usually would be suffering with on day 2! And my boobs usually would've been feeling less sore by now, but they're still hurting. I tested the day I was due though, and it was negative, and I would be pretty surprised if I was pg. But this is pretty odd AF behaviour. Has there been any change for you, notquitesure?
