I got some from Motherhood maternity (online) that work pretty well. They can be folded down under your belly if they're more comfortable that way.
I wear granny panties :( my husband makes fun of me lol and ice recently found (for the days I'm.feeling really.good or I wanna dress up) that strictly lace panties or thongs work amazing! They are surprisingly comfy. I bought them for.my.honey cause he.likes them so they originally were only.meant to.be worn a few minutes lol now.I wear them pretty often actually.
Low-rise cotton panties, they rest under my belly just fine. I'm still wearing all my panties from before sincel they are all low-rise anyway. Even pick up a few extra pack due to the heavy discharge toward the end of the pregnancy. 33weeks here :)
No panties..or granny panties if u must.. cotton all white no color
the ones from motherhood maternity work wonders for me. Even ones at target are nice too.
Size 16 -18 (UK size) of the big panties that come in cheap multi packs! Bra extenders (from eBay), wireless bras too.
