Pregnancy advise

Chanelly
So I am currently 9 days late ! I bought a clear blue test but literally only peed a drop of pee on there ! Not a five second pee a ONE second , came back not pregnant ! Could it false ? Am I pregnant ? Should I wait to take another one or what? We aren't trying to have a baby but if it happens it happens ! Please any advise ! I don't feel pregnant as my first child I was so very sure I was pregnant !
