I'm so confused😩

Sally
Ok I'm sure people think I'm crazy but I don't understand my body! Been off birth control for a year and a half, I'm a very regular person usually and I'm not stressed until now! Ok so I am a little over a month late I've had several pregnancy symptoms but all negative test including blood. I started my period yesterday but it's already over. I feel pregnant I'm sure it's all in my head but I don't know I've had an ultrasound done and a crap ton of bloodwork done and I will get those results tomorrow! My question is am I stupid and all this stuff is in my head or could there really be something not right! Has anyone had this happen to them before?!?
