I had the implant fitted just over a month ago. I am usually a 32B (much to my dismay) but I noticed I was spilling out of my bras and was finding they were very tight and after taking them off, my boobs would hurt. I went and bought a bra in a 32C instead to see if that was better but I still had a weird looking cleavage and tightness. Eventually I tied a 32D and have found the cup size is a lot more comfortable and covers me properly with no spillage, although the back is a little tight so may have to try a 34D.
Anyway, I know the implant can make your boobs tender etc but can it cause them to grow? It's weird because to me it doesn't feel or look like they've grown, they don't look like what I imagine a D cup pair of boobs would look like as in they're not humongous. But evidently they must have grown if I can't seem to fit into a B or a C anymore.
I've gained a bit of weight around my hips and tummy whereas since recently I was a size 6 and now have trouble getting into an 8 (I'm aware this still isn't a bad thing!) but I know the implant can cause weight gain.
