Anyone in a similar situation I'm 17 days late I have no idea what's going on with my body I never miss a period I'm certainly not stressed took a test yesterday it was negative. I'm just afraid to start my dieting and gyming strenuously till I'm sure. My last period was March 22-26 should I wait it out longer or accept its negative but I have no sign of any period coming.
