Anterior placenta ... Anyone else?

We went to our anatomy scan today. I am 22 weeks. Here's our baby girl, Annabelle Rose. She is perfect in every way ... The only thing my doctor seemed a little concerned about was the fact I have an anterior placenta ... That is sitting a little low. She said it most likely will move as my uterus grows but it's still worrying me. Do we ever stop worrying in pregnancy!? I just want April to come so I can hold this baby girl!
