What should I do?

Ja

I had some heavy bleeding and slight cramps the other day. I’ve had an ultrasound and gotten blood drawn. My app currently has me at 6 weeks but blood shows around 2 weeks and there was nothing shown on the ultrasound. My doctor feels I’m still pregnant due to my symptoms increasing but i feel like i need to really know. I won’t know the results of my second blood test until Saturday. Should i take another test or should i wait for Saturday?
