Uh oh... My pants are starting to get tight...

HELP!! My jeans are starting to feel a little tighter around my waist as I enter into my 8th week with baby #2. My tiny bump (and the steak and cheese sub I had for lunch) are making it a little less comfortable to wear my normal clothes (and look nice). 
Do any of you have some suggestions for where I should start maternity shopping? Preferably somewhere that won't break the bank! I got a baby to save for! 
If it helps, I'm in the Midwest (Western Wisconsin) and I'm not against online shopping.
