Not sure what to think

So a little background, I’ve been ttc for approx 13 years , never even had a scare of being pregnant dat forward to dec 18th I tested positive! Got blood work that morning Hcg 3097 progesterone 9.4 , was started on progesterone but was not able to start it until the 20th due to stock , blood was redrawn the 20th morning Hcg level came back as 2616 progesterone 7 , well went in for ultrasound cause I know what dropping levels mean usually , well the sac , and fetal pole is there I was measuring good 6weeks 1 day but they couldn’t t see/hear a heartbeat , had labs redrawn and I go back next week for repeat ultrasound . The doctor said there is hope but I’m struggling to think so I’m not having any miscarry symptoms so idk I don’t wanna get my hopes up but also tryin to stay positive, anyone else have similar situation ? O I do have pcos!
