We had one good quality blast on Monday afternoon. All has been well since then apart from some cramping on and off. This morning I woke up to some bright red bleeding (about a tea spoons worth) that seems to have tailered off at the minute, I phoned the clinic earlier worried and got the nurse (who isn't the most sympathetic with her telephone manner!) and was told it could be not enough progesterone or simply that it might not have took or just unexplained I need to wait another few days but if it continues its probably safe to assume it hasn't worked. Any one else come across this and had a positive outcome?
