Nursing bras. I didn't actually need them while pregnant and I sized up so many times they were a waste of money. I would have been better off buying a couple of comfy cheap bras every couple of months.
Belly band ... if regular pants aren't fitting, just go get some maternity pants, you won't regret it! Or just live in yoga pants or leggings. Comfort is key!
