Sneezing

I don't know what the deal is... Is there any correlation between pregnancy and sneezing?? Perhaps it's just my own weird preggo thing. Pre-pregnancy, I probably sneezed once... maybe twice... a week. Now? Sheesh... it's like 2 or 3 times a DAY! What's going on here? My nose can handle only so much tissue wiping! And I don't have any allergies that I'm aware of. Hmm. I asked my nurse and she didn't have a clue as to why I'd be sneezing so much. I guess for now it'll remain a mystery. :)
