Not that it make much difference now. In 1983 and 1986 my wife and I took vacations to various dive sites. I have been diving forever but my wife was newly certified.
She couldn't stand gearing up with the suits, BCs, tanks, etc. Worst of all was the smell from the diesel engines. She was glad to get into the water because she was really seasick.
Eight months after each of these dive vacations, a "little bundle of joy appeared. It seems that her seasickness was actually morning sickness! She was pregant both times and wasn't aware until she returned home.
My wife no longer dives(thank goodness--I can't take any more kids)--just the thought of being on a boat rocking back and forth makes her sick. "The Perfect Storm" was agony for her. Even "Titanic" made her sick! I'm not making this up.
