Rainbow baby stories

Hey girls, I had a chemical in June last year, followed by a missed miscarriage in November at 8 weeks, I found out I’m pregnant not long ago, I’m 4w 5d, I have an early scan on the 30th March but I’m so terrified that I can’t get excited all I want to do is cry I’m so scared I just want reassurance my baby is okay. Can anyone please share any rainbow baby stories with me? I’m over analysing every cramp, ache, twinge like it’s the end of the world and wiping like crazy to check there’s no blood. Any positive stories would be amazing please, thank you girls in advance. I’ve never carried past 8 weeks💛
