The earliest I would test with a hpt is a day or 2 before your period is due, or 14 days past ovulation, if you know when that was. Those could be symptoms of pregnancy, or they could be period symptoms as you said. You know your body, you know if something is different. Good luck!
I have the same symptoms my period is due the 13th........I wonder if I'm preg...... last month my period was 2 weeks late......
