I'm 12 weeks pregnant and am currently spilling out of my (already generous!) bras. The waistband is also now uncomfortably tight and has to be undone when sitting down for long periods 
As this is my first pregnancy, I'm not sure what kind of bras I need to buy now. Do I just go and get re-measured but buy normal bras (these are expensive tho as already have to go to Bravissimo) and then also buy nursing/maternity bras when the baby comes? Or do I buy nursing/maternity bras now and wear them till baby comes and after? What kind of bras are good when you don't know how much bigger your boobs will grow? Don't want to spend too much money if I can help it, but would like to be comfy!
