these have worked perfectly for me while I'm in my 1st trimester. This is my second pregnancy and I felt like I started to "pop" as early as 10 weeks! And I definitely had a lot of bloating. It was way too early to break out my maternity clothes, so I've used these to wear over my regular pants so I could fit into them without buttoning them! The package comes with button extenders, too, which work great when you're too big for your regular size, but too small for full panel maternity coverage. I might even continue to use these as I get bigger. As long as your legs/bum don't grow too much, you can still fit in your pants and just cover up the opening. You do have to consider what you wear - you cant tuck anything in but the bands stay up ALL day, dont roll down, and dont compress my stomach. Very happy!
