Good luck with your upcoming procedure to place a new port. I have had mine for 3 years and LOVE it. Have you thought about where you are going to have it placed on your body? Mine is in the standard and common place, upper-right chest-third rib from top. My port does stick out, so I can't wear strapless or spaghetti straps, and even some tops with thin straps. Bathing suits are a nightmare to find, because none of them have chest coverage that high (unless it's aqua swimsuits that are less than flattering). My port sticks out, even though it is the slim bard power port, because I am thin and have no fatty tissue in my upper chest. This is a big issue that you need to discuss ahead of time with the people placing your port, whether there are different options in placement of your port. I have heard of women getting the port placed between their breasts or under the armpit.
Also, I was quite sore for a few days. I got a prescription pain med and was glad for it. I doubt you will have pain for 2 weeks, if you even have pain, everyone is different. So, enjoy the wedding and good luck with your new port!
