I found a bald spot :(

I found a bald spot on the back of my head near the top, about the size of the pad of my thumb.  I am currently pregnant.  Should I be freaking out?  I am too scared to google. 
I thought you were supposed to have more hair while pregnant.
Anyone else have this issue?  Is this a rush to the Dr. thing or should I wait for my next appointment?

I still lost hair while pregnant, the same amount as usual. I think the not losing hair while PG is overstated. Anyway, can't hurt to ask at your next appt.
