I've had a couple of erratic periods after being regular as clockwork. One very looong cycle (7 weeks, did p tests, all negative). Then a short 3 day bleed. Have now had early pregnancy symptoms for two weeks and a negative test (probably testing too early).
For a more conclusive test do I do one on the basis of an average normal cycle for me... or as I had a short period should I get a true result earlier? What is the general average anyway????
