Does a pregnant woman's vagina have a different odor to it than a woman still getting her period?

Is it normal for it to smell pretty bad during pregancy?

Not that I am aware of... and given your question in the 'dungeon' thread if you partner is pregnant be very, very careful about playing BDSM games

Sorry. The pregnant question is unrelated. My dungeon partner is very spry.

I have noticed that the scent increases some in pregnancy. Hormones and secretions are way up during pregnancy which can definitely affect the overall scent produced as well. Possibly some additional cleaning will help this, but I don't think it will entirely do away with the issue.
