Not sure here either... I love the idea of the tummy tuck after you finally have a baby. That would be idea

so I think I'd lean that way but if you are starting to feel pain/pressure then I'd really reconsider that. Bottom line, I think, since it shouldn't affect pg, I'd leave it as long as I could (so I could get my tummy tuck later) but if the pain got to be bad enough, I'd just get it removed now though I do think it will probably cause you to have to put TTC on hold.
