PG & sex: Your treating OB MD can give your the "last word" on this subject if you ask. However, generally, most pregnant partners can continue active intercourse with a couple of major exceptions: 1) Active vaginal bleeding 2) Ruptured amniotic membranes. As the pregnancy progresses, positional variation for female/fetus comfort is advised.
