Maternity Workout pants

So I’m starting back working out next week (18 weeks pregnant), but am in dyer need of some workout pants.

Tried on some at Target that are too long and a lil see through and I live in Florida. So don’t want to cook myself and the baby.

Went to Motherhood maternity last night and they were too thin and see through.... anyone know of any brands that sell crop length, non see through workout pants... not leggings, but workout pants.
