Early ultrasound

Missy👸🏾
5wk2days today & was given an ultrasound BC I was bleeding & cramping. My ob said she believes its just my last period BC I found out so soon. Well today they couldn't see anything on my scan so I'm just awaiting my blood work tmrw. I believe that I'm sooner then 5wks that's why nothing was seen. But I'll know more tmrw. Has this ever happened to anyone?? Plus I took another test today is my lines are getting darker. Actually this is the darkest its ever been. So I'm feeling very positive about this one
