I had positive tests and they were getting darker. I went to the doc because I bled for one day. Ends up I passed bladder stones and as soon as that was over no more bleeding. Doctors say my urine and blood is negative. But my period is now officially 8 days late and my morning sickness has not gone away. Along with all the other symptoms. The tests though are not getting darker. They are staying faint. Should I schedule with my OB or what? I was last seen 7 days ago.
