After you stopped breastfeeding?

How long after you stopped breastfeeding did your boobs stop changing size?

I stopped 7 weeks ago and don't want to have to buy new bras if the are still changing. My nursing bras are to big and my pre pregnancy bras are to small. I was a 34DDD before pregnancy and now I would guess a 34G. I've been wearing sports bras most of the time as they are the only ones I don't feel like I'm falling out of.

We are hoping to be expecting again by the end of the year also and with my daughter by 8 weeks I had gone up a size. So not sure if it is really worth even trying to find something right now or not.

I know everyone is different but wouldn't mind some insight from those who have been through this before.
