Upset, confused.. needing something just not sure what

Last night I went to the ER.. I had estimated myself at 6wks pregnant. I had been having really uncomfortable cramping and some very light bleeding with quite a bit of sticky clear discharge. So I went to get checked out to be safe, after arriving at the ER they had done blood work and an ultrasound the ultrasound showed a gestational sack and egg yolk measuring at 5wks 3day which after inputting into the app makes sense since it says my ovulation day was dec 10 and that’s when it says I would have conceived. Now after talking with the ER doctor he said there were several conceding factors one being my gestational sack was measuring smaller than they would have hoped and that my HCG level was 4300 which is less than what they would expect to see he said they would want to see more like 10,000, he said if he had to guess I would more than likely lose this baby but couldn’t be sure but then said again I probably would miscarry. I was heartbroken, I left feeling confused. I was told to call my OB Monday.. I’m upset, I’m confused, I don’t know how to feel except numb because I felt like I wasn’t given any real answers. Just looking for advice maybe compassion, I honestly don’t know.
