Pregnancy symptoms no one talks about.

We all hear about the nausea, the vomiting, the tiredness, the periods of increased and/or decreased appetite... but what are some things you had no idea about going into pregnancy? For me it was that awful taste I had in my mouth the first 4 months and the stuffy nose! My nose has been stuffed since November! I've subconsciously resorted to mouth breathing which has had my lips chapped all pregnancy! Also, I knew I'd be tired but at week 37 I run out of breath walking across a room! LOL What is something you've experienced during pregnancy that you weren't warned about before hand?!
