Please Wish Me Good Luck !

So today I have an ultrasound i'm currently 12 weeks + 2 days I haven't had an ultrasound since I was 5 weeks and maybe i'm over reacting but since we only saw the gestational sac just please wish me luck i'm happy to finally get another ultrasound but at the same time so worried. What if there's no baby or even worse .... :( I don't even want to mention it. But seeing stories on here of mommies loosing their babies is so heartbreaking to me 💔 I hope my lil one is okay! I always worried about my daughter when I was pregnant with her and now with this baby i'm more calm but I won't feel any sort of relief until I see a baby in the ultrasound with a heartbeat
