Originally when I had Sierra just before my 18th birthday and then Will followed just after my 21st (back when I was naive and didn't have a clue what SI was) I said I would be done having babies by the time I turned 30. That's in 6 months. Obviously, I am not going to be done by that point. I have told Matt that I will never prevent again using birth control(regardless of whether we have another or not we have more) If we do ever feel the need to prevent I will be using NFP or charting to avoid. I don't see even that happening though.
Right now our plan is to try a few rounds of IUI during the spring/summer. If that doesn't work, we will be NTNP while we save up the money (or find loans) for IVF. My doctor has a
cost share program. We will use that program, and will do up to 3 fresh cycles and as many FETs as we have embryos for. At that point, if we are still not pregnant we will be done. We won't prevent, but it looks like that by my 32 or 33 birthday we will be done trying.
