To early for Maternity clothes??

Amanda
I'm almost 10 weeks, and my jeans are already really uncomfortable. And since we are waiting a few more weeks before we announce I don't have an excuse to wear stretchy pants all the time.  I've been debating on just investing in 1 pair of maternity jeans so I can be comfortable, but not sure since I know I'll just be getting bigger. Lol 
Anyone else having this issue. This is my 3rd baby, and I never showed this early with my others.
