Help! Calling all big breasted mamas!

I need help finding a maternity bra!

Before I was pregnant I wore a 38G. I was able to wear a normal bra in a 40G for a little but then started flowing out and wearing it was just making me sore.

So I tried to get a maternity/ nursing bra from Motherhood Maternity. I went up to a 40H (my band on the G was not hurting me).

Well the band doesn’t seem as big and my boobs are falling out more than with the 40G. Im not concerned about trying to return them but I NEED to find a maternity bra that works for a larger cup size.

Any suggestions will be accepted gratefully!
