Yay. Congratulations, how exciting. The time will fly by.
MYA recommended Macom, but Marks and Spencer, Amazon, Ebay, New Chic, H&M and Primark all do zip front sports bras. The nurse will go through the best bra and what you’ll need, but you’ll need a couple (at least) as you’ll have to live in them for 6 weeks.
Hope this helps
