I went once.
After not beeing able to breath for two hours during never ending breathing exercises - well...yes I have been having a pleasant "rhinits of pregnancy".
After not having been able to find my perineum muscle (if you know where and what it is, you are a lucky woman - If you survived up to now without knowing it, I am pretty confident that you can do the same from now on).
After looking at myself in the mirror while I was doing important excercises such as rotating my wrists and moving my neck back and forward (I totally looked like a helicopter with a pink skirt on).
After still not knowing how to change a diaper.
