Pregnant and working in the medical field

I wear scrubs everyday to work and was wondering if there’s anyone similar that’s dealt with it and having to buy maternity scrubs. I’m 19 weeks pregnant and still in my old scrubs but it’s starting to get uncomfortable for the pants. What brands are the best? Did y’all have to order them online I’m assuming? Also have y’all been able to get away with just buying maternity scrub pants and not the top? Am trying to save money if possible..
