Thanks guys, i'll wait then and see what happens
They symptoms you describe just sound like pms, like your period is due to arrive. Of course it could be due to pregnancy too, but since you tested negative, I would say it's unlikely. Wait another week, and if still no period, then test again or go see your doctor for a blood test - that will tell you for sure whether you're pregnant or not.
i would wait and retest in a few days
id wait it out a little while and re-test. if your still not having a period and still have the symptoms after another negative test, i would consult a doctor.
