I'm five days late, and I have taken like five hpt (all of which were negative). I'm super crampy and every night I feel sick, and have low back pain. I have two children and the hpt should me two Weeks before my period was even due. I have had previous issues with ovarian cysts but they have never affected my period. Please help me!! The earliest I can get in to see my OBGYN is Dec 7. Thanks in advance fir the help.
