I didn't use one with my son, but already clothes are not fitting.
So my question is: is it worth the 30 bucks for them, and how big/small do they run? I am started out between a 14-16, and that is the size change. I have no hips what so ever so I am leaning towards the smaller one, but I wanted to hear from people who use them first.
TIA

Re: Bella Band question
I got the version they sell at Motherhood. I thought it was worth it--I was able to put off maternity pants for another month or two with it, and that was definitely worth it for me. I plan to use it again this pregnancy once my pants start getting snug.
Not sure about sizing.
This. I don't need it yet but when I do I will be getting the Target version.
This is what I've been doing. I put my belt on over the hairband part as well as my longer shirts and you can't tell I haven't buttoned my jeans. My skinny jeans are actually more comfortable than regular jeans right now, I think because they are low rise.
I also have a few pairs of pants and shirts from when I weighed about 10 lbs. heavier so I think those should be able to get me through until it's time to break out the maternity clothes my sister gave me.
