Between regular and maternity clothes?

I am now 9w2d with baby #2. I am starting to feel uncomfortable in regular jeans but if I use maternity jeans from last time, they kinda slink down a little since I dont have a bump big enough to keep the jeans in place. What should I do to wear comfortable stuff? I work full time so I need clothes fit for work, I only wear jeans to work so that part is ok though.
