7 wks - ultrasound shows nothing

Brianne
Help! I'm slightly freaking out. It's my first pregnancy, I should be 7 weeks today and now 3 pregnancy tests show positive (one was at the doctors), but the ultrasound showed nothing. So now bloodwork done today and I go back again Friday.
Anyone ever have this happen? I have no pelvic or belly pain, or bleeding. Really hoping this is not an ectopic pregnancy. 😕
