Hey girls ? Do contractions start even if the baby's head isn't down?…

Hey girls ? Do contractions start even if the baby's head isn't down? My belly hasn't dropped yet at 41 weeks, I have an appointment on Monday to be admitted to the hospital, but I don't want to go ? I'm so worried, they also said there's a partition in the vagina and it will be cut off then sewn up. So much is happening with the birth, I'm scared ?
