I've been exactly the same with quite painfull bh, and some pressure pain like every now and then. I sometimes get the feeling my waters are about to break or baby is gonna fall out. My back pain has been insane and i have absolutly no energy and i know what you mean about looking after another child, my son is 3 and quite demanding lately. I went to hospital during the week and they said my baby is 3/5th engaged so i hope its not going to be too much longer. Id love if my baby came 2 weeks early!
