Like you, we *knew* it might be a struggle to have another baby so we started trying when DD1 turned 1. Nothing was happening and we started to get serious around four months later. Fast forward through three m/c, numerous alternative medicines, clomid, lap and dye, IUI and IVF and we finally have a nearly 9 mo. Our eldest is 6. I never wanted this big age gap but really wanted another baby. Would i change anything? No, its worked out wonderful but during that whole process I was close to breaking point. I guess what I am saying is that you only know when is the right time and know that any variables could present themselves such as falling pg straight away to the other end of the spectrum and to not have any expectations of what *should * happen and when. iTMS? Huge hugs its such a huge decision to make when you have variables against you. Just a thought, what about you go with not preventing/not trying and see where the universe takes you? X
