Help!!! Need answers...

So i dont know what's going on and I'm so confused! Yesterday I started with some light bleeding it was light pink (was not a lot) then later on around 8pm I started bleeding a little more and so we decided to go to the hospital did a urine sample and when I went to pee there was dark blood on my underwear then we waited for a while then they did a check up said my cervix is closed and there was just a little bit of blood then they did and ultrasound and they saw the sac empty but no blood around the sac which was good and that is shows I'm 5weeks and 5 days pregnant but m LMP was 03/31 so I should be 8 weeks and 1 day pregnant. So then they decided to do a blood work and a hormone test, blood work showed I was pregnant and the hormone test game back high showing I was 8 weeks pregnant. Then the doctor said its a miscarriage but then later he said that it could be early to see the baby. Then I was released leaving with no answers and told to call my OBGYN to schedule an appointment cuz they want to monitor my pregnancy . I'm home now and the bleeding is super light and it's a brown color. So please help me understand what's going on!!! I'm complete list and worried!!!
