9 more weeks and this is to much?

at 21 weeks by baby boy was diagnosed with ccam and since then all the frequent ultrasound have been good the baby hasn't develop hydrop and the ccam has not increased in size, i;m praying it will disappear. so i had to get transfer to a high risk pregnancy clinic and at my last ultrasound i found out my baby has only one umbilical artery, when they told me i ume it was a common thing because they didn't explain much about it so i didn't think about finding information. but for some reason today it came to mind and i look it up and it says that babies with one umbilical artery amy have abnormalities and know i'm scared, i mean i'm still going to love this baby but nobody told me the one umbilical cord till like a week ago, i'm so scared, i want my baby to be healthy i feel that i have already failed as a mother and i know it's not my fault this has happen, but i feel like i fail to my baby and my husband. i have this feeling that my baby is gonna be fine but i'm still scared i don't want to think about this i don't know what to do? and i feel bad telling my boyfriend because i know he will be worried. this is our first baby and i'm also scare to get pregnant again in the future.
