Help!

So Friday my husband and I found out I was pregnant by blood test. They never said my levels or anything but today I started bleeding. I went to the hospital and said my levels were low. They did an ultrasound but I’m to early for them to see anything and this was after the ultrasound. Could this be implantation bleeding or am I miscarrying. The doc said he couldn’t say either way because I can still have a normal pregnancy
