Anatomy scan! Nervous..

So when I have my anatomy scan I will be 18w6d, which is pretty much 19 weeks I know 😂

But I just feel like 😣 what if something if something is wrong with my little baby boy!):

Sometimes I don’t always eat the healthiest I do admit and I will forget to take my prenatal sometimes, I have this fear something I do will cause something to be wrong at my anatomy scan😣💙!!
