Af due on Saturday. It is now Thursday morning. I have done a test every morning since Saturday and im still getting bfn! I have several symtoms. Constantly tired! Nausea on and off throughout the day. I went and bought a new bra yesterday and went up 3 cup sizes!!!!! 3!!!!! My boobs are also very heavy and itchy! I also have a huge increase in cm. Goes from creamy to watery to ewcm. Could it still be too early to pick up on a hpt?
