My baby boy!

I got my very last ultrasound today of baby boy (21 weeks) which sucks. With my first I got ultrasounds every month (high risk) and with my second I got one like every 2-3 months (also high risk) this is my first non high risk pregnancy so they’re done with ultrasounds now. (Unless something changes and I fail others tests or my ob says otherwise etc) but I’m so sad I have to go 18 weeks until baby boy comes with no more ultrasounds. I’m scared tho like what if there’s low amniotic fluid or something wrong and they can’t tell with out ultrasound 😪😪
