I would be careful with your breasts as the incisions and tissues are still healing. If you have any concern that there might be an issue, I would contact your plastic surgeon.
I would also recommend returning to your surgeon for an assessment. Avoiding crowded places where people can bump into you, and warning friends and family that you can't be hugged tightly due to surgery (they don't have to know what type of surgery) is best for the first 6 weeks post operatively.
