Ok I'm freaked out!

Laura • Hi! We're pregnant with our 3rd baby. My husband and I are both 30 and we have 2 boys 10 & almost 4 and are very excited to have a little princess now ❤
I had my ultrasound today and they said I have to go back for another one because they saw what looks like a possible cyst on her brain. They also couldn't get a good picture of the bottom of the spine 😕 everything I'm reading says that it normally takes care of its self but it's still hard to not worry.............has any one else has this happen?
