Is gas an early sign?

Kristina
TMI, but I have had HORRIBLE gas the last two days.  I'm talking all day, frequent, incredibly smelly farts that I can barely control.  My husband and I have been TTC #2 for 6 months.  I did not have any early signs with my first other than missed period.  I am 2 days from my expected period.  Is this gas a sign that I am pregnant?  Is it too early to have symptoms like this?  I haven't taken a test because I'm frankly too scared to get another no.
