My first pregnancy 4W3D

Emily

So I am absolutely petrified that this pregnancy will turn into a chemical pregnancy. I have had many symptoms such as sore breasts (which i don’t normally get), slight cramps, headaches and tiredness. My symptoms have been coming and going, is this normal?? I have not yet technically missed my period as according to Glow it was meant to start on Monday. Am I stressing over nothing as the clear blue digital came up positive??
