Maternity clothes

I haven’t brought much luckily, but I’m going to have to succumb to a pair of bottoms ideally jeans/jeggings so I can wear a top and not worry about my bum being on show through poor quality leggings. But I think I’ve ordered 5/6 pairs and they’ve all gone back because there’s just nothing to keep them up! The ‘jean’ part is really low rise and then because the bump band attached doesn’t have enough strength to hold them up they just fall down and I feel uncomfortable. I’ve ordered from New look, ASOS, next. Reluctant to get them from Topshop because of the price and they’ll only be used for like 8 weeks now.
So any recommendations for well fitted ideally over bump maternity jeans?
