Trying to relax!!

I have my first u/s tomorrow at 6 weeks 1 day. 2 previous losses this year and I can’t help but shake the feeling something isn’t right?? Felt great about everything up until today. Don’t know if it’s just nerves? My hcg numbers were 4426 at 4w5d and 14,016 at 5w1d so that is positive...had sore boobs and morning sickness pretty constant til yesterday. Now my boobs aren’t that sore and the m/s seems to come and go. This is my 5th baby so I should be used to all this by now but just can’t get excited til I see a heartbeat and know everything is ok! Asking for 🙏🙏 🌈👶🏼
