My last period ended on july 20 09 n around august 12 I had a pinkish discharge only on that day. I still have not had my period n I have a egg white clear discharge no odor everyday. I took 3 hpt but all came back neg. I called dr for blood test but they said I have to wait till sept 3 bc than I will be exactly 2 wks late. Is it possible for me to pregnant n that I took the hpt tests too early?
