I thought I might have been pregnant and tested but got BFN. My symptoms continued and was late so tested again and thought I saw a faint line. I was going to test again using clear blue digital but then my period came (I thought it was) by only lasted 2 days and wasn’t particularly heavy. I have very tender breasts, tired and have felt a bit nauseous. Could I be pregnant? My periods usually last 5 days. Anyone had something similar and any advice what to do?
