I'd get a nursing bra. That's what I did. I'm 30 weeks now and waited way too long to get a couple of nursing bras.
Go for a nursing bra! Message me I can give you amazing recommendations. I do reviews for maternity and nursing bras as a hobby lol!
Depends how big you are. I was a 34E and now much bigger during pregnancy and sports bras have zero support, look awful under clothes and are super uncomfortable 😅
I got some nursing bras at like 8 weeks because my boobs we’re so swollen and sore- I love them! Great support and very comfy- mine are kind of a sports bra style in a way. Pretty adaptable in size as well
I would just get a nursing bra or sports bra. Buying new actual bras regularly is expensive
