I was banded March 2012 and became pregnany Sept 2012. It is now June 2013 and I have an 8 week old baby girl.
My port 'bothered' me months 7 on, just because my belly was so big. By month 9, my port had turned ( flipped) so it was uncomfortable but not painful. Now, 2 months postpartum my port is loose. I am back down to my pre pregnancy weight, but obviously the port was 'pushed' around with my growing uterus. It still moved. At this point I'm not interested in more surgery to re-attach. I plan to loose more weight ( modified band diet as I'm breastfeeding) as well as re-assess in a year based on my body getting back to it's post pregnancy state. Not sure if I've helped , but port site was not painful. I guess my point is that anything can happen , you just assess as you go on. I'd like to suggest your health for you and eventually having a healthy baby might be worth a little discomfort. It is for me. Best of luck.
