Cyst on ovary in pregnancy?

🎀 Nat 🎀 • Baby Girl Mom/ May 2019 💖 #Babynumber 2 due March 2021 💖💙

Had my first u/s today! Baby had a heartbeat! 7+ 2 due may 22nd. They mentioned that i do have a 6cm cyst on my right ovary, i am quite concerned but heard they do usually go away. Anyone else have this or had one in previous pregnancies?
