Thanks everyone! In the a.m. after taking off the Brava domes I'm spilling over my B cups but by the evening I'm fitting in them with a tiny bit of room to spare. So yeah, the bra calculators are just plain wrong, at least in my case. No way these would fit into a 34A when fully swollen! And I'm happy to say that I've gained a full inch since beginning, so I'm going to be saying goodbye to all my A size bras. Good riddance!

Measure your underbust and round up to nearest even number, then try different cups till one fits. You can then measure your overbust in a properly fitting non-padded bra to get a more accurate result
