First two strip tests were from this morning and this afternoon, clearblue digital from this evening states not pregnant? I convinced myself maybe I hadn’t enough urine when dipping the clearblue but after reading the leaflet, if that was the case I think it would have come up error as opposed to not pregnant. Don’t know what to think! Has anyone else ever got a false negative on a clearblue digital? Period 4 days late and severe nausea with a few episodes of vomitting
