Has anyone else had this? I had lots of positive tests on Tuesday and clear blue digital saying 1-2 weeks. This would mean I'm 4 weeks 5 days pregnant. Had cramps 2 days this week and now today clear blue digi says not pregnant and there's no line on normal test. I rang NHS direct and they say it's probably fine and that chemical pregnancys are rare? Personally I don't feel pregnant anymore but they were quite positive on the phone. Am I still pregnant or not? They say I just have to wait which is so hard! Any advice girls?
