Went to the hospital last night

The hospital said I had a uti, and that my bacterial infection was gone yay but they took a sonogram and they couldn’t really get a heartbeat and the heartbeat she think she got was on at 96bpm and it’s supposed to be higher, so there’s still a chance for a threaten miscarriage, I’m 6w3d today. thankfully they gave me a excuse for 2 days off work but I’m already off one of those days.. I’m so worried but I need to stop cause it’ll only make it worse. I’m asking for prayers please, my first time pregnant after not thinking I could. TIA!!
