I say, and with God's help: If intercourse occurs due to the cessation of bleeding for ten days, it is permissible. If it happens after the time of prayer, for example, she became pure after Maghrib and had intercourse after Isha, it is permissible. However, if she became pure during a prayer time for less than ten days and did not perform ghusl, then intercourse with her is disliked. And God knows best.
