Possible placenta issues

Mama🐻 • SAHM 👨‍👩‍👦‍👦 married my best friend 💍 boy mom x2💙💙

At the gender ultrasound they found that the placenta is 2 CM away from my cervix. they are going to do another ultrasound d at 30 weeks just to monitor it and said that I shouldn't be worried at this point cause it could be just fine. but with my anxiety I literally don't go 5 minutes without slightly freaking out about it. if anyone has had this issue or has been in the same shoes I would appreciate any and all advice at this point...
