Worried alot right now

I am currently 4wks and 3 days. I went to the hospital today because I was feeling crappy nausea, headache, and cramping.

They did an early ultrasound and discovered a subchorionic hematoma ( a bruise as the Dr said) between my uterus and the placenta... He said small ones don't usually cause issues but I should see my ob in 1 to 2 days... Well I can't see them till Thursday. So what do I do to keep from stressing or making the situation worse until then?
