Swimming in 3rd tri?

RedRose87

My husband thinks I am crazy...I really want to go swimming but I have a concern. My son is already head down at 34 weeks and I am really hoping he stays that way. He's really low so I am hoping he is settled in already. Well I guess I am worried that swimming might somehow, I don't know the words exactly, but make him buoyant, or make it easier for him to turn in there into a position that is not preferred. Does anyone know if swimming can cause him to go from head down to, say, a breech position? I know this probably sounds really dumb, which is why I don't want to ask my Obgyn and my husband insists it isn't possible for swimming to have an effect.
