Hi Diva,
I second (third?) the recommendation for the ABA/mother's direct shop. I'm a 14G so I know EXACTLY what you mean about missing the days of underwire. I got three bras from them- Hot Milk, Triumph and HoneyBee, the brands were. Don't bother with HoneyBee; I only wear that unpleasantly scritchy thing when the other two are in the wash. Hot Milk are superbly comfy and really really pretty as well, but Triumph give by far the best support- I plan to wear my Triumph one when I start netball again in a couple of weeks. Believe me, if I don't wear something with excellent support when I'm running, I'll be knocked out cold by my own bosoms. Triumph, unfortunately, would also be approved by the Taliban as far as modesty and coverage go. Oh well.

I hope you find something that lifts and supports and DOESN"T give you a migraine. Poor thing!
Oh, and congrats on the pregnancy!
Kirsten
