I got new ones at about 5-6 weeks, I just sized up by one size. I'm now 16 weeks and deciding on if I should size up again. Just find something that's supportive and comfortable, buy at least 2, and then size up if need be later on. I got mine at walmart on clearance 😅
I got the two packs from Costco and sized up
I got some really cheap ones at Walmart (I forget the name of their brand but it's like "Simple"- something or something like that. They were maybe $10 and are quite supportive. Nursing sports bras.
No 😣
I double up with a nursing bra and sports bra for extra support
