Just like @JeanneAdilsaid, wait till the embassy instructs you to redo your medicals because you don’t know how long it would take after you submit your documents to issue your visa. When my husband was placed on AP, his medical was less than one month old but because he was in AP for almost 6 months, the embassy had to instruct him to redo it when the AP was over. We didn’t take any step when it expired until he was told to do so.
