Really embarrassing question!

Ok this is embarrassing. I'm 22 weeks pregnant with my first baby and tonight was the first time I shaved my lady parts since I've been pregnant (I have just not had the energy!) and I noticed my vagina is so swollen!! The outsides are so big they've never looked like that before! Is this normal? I'm assuming more blood flow to the area is causing it? Someone tell me it goes back to normal after birth!!! :(
