As the title says, on the 23rd of its month I got a positive result in a test putting me at around 4+3 weeks, so to confirm I got one of those clear blue weeks indicator tests which this morning has come up saying not pregnant. I'm super worried and concerned and waiting on call from docs. Has this happened to anyone else? I have every symptom going with no bleeding at all, should I be concerned or have hope everything will be ok?
