Quite random really, although slightly pertinent. Why, when you have a bath, does water not enter the uterus through the cervix?! Fluids can come out, sperm can go in, but apparently, according to google, water doesn't go in when you have a bath but no reason why given? (Admittedly only a cursory look on google!).
See, completely random, but was crossing my mind when I decided not to have a bath (just to clarify, I did wash in other ways 
) just in case during the dtd week! Ridiculous the things you think of whilst Ttc....
Anyone medically (or more thorough with google) shed any light?
Hope this passes some time for those in the 2ww.
