Worried

I am 5 weeks and 4 days pregnant and had to go to the ER due to my light, pink spotting becoming heavier and red. They diagnosed me with “threatened miscarriage” but said the sac and everything looks fine. (Too early for a heartbeat and visual of baby). They sent me home and said to come back in 3 days to test my HCG levels. They also told me to follow up with my nurse practitioner and my ob but I am stressing because I have to wait a whole week in order to see both. I am trying not to stress but not knowing what is going on with my baby is driving me crazy.
