Tanya around 8 weeks mine were the same. They kind of exploded but after another 1.5 weeks calmed down a heap in size & soreness. Have you thought of going to an Op shop to get some cheap bras that may give you some temporary relief from what you have now? I got fitted @ 8 weeks (up 3 sizes!) but am now only 2 sizes up, so this bra didn't have much use.
