Bigger Pants

Ok ladies! I know we will each have different experiences with our pregnancies... I have had to have limited activity/exercise (currently 9weeks) due to drs orders. I haven't been on a scale but I know I've gone up 5-10 pounds and have major bloat in the afternoon/evenings. Also, ive been eating all day to keep the 'morning' sickness at bay...MY QUESTION IS....when did you buy bigger pants/jeans?
