more discharge??

hi mommies to be, may I ask if its normal to have more discharge during pregnancy? I'm having alot of discharge, but in mild yellowish color, no itch, no burning sensation etc. I used to wear 1 pantyliner a day, now I need to use at least 2. it kinda worries me... cause its mild yellow plus I'm having more now. would love to hear ur experience! I'm about 9 weeks now though..
