Congrats on your successful IVF! We had IVF/ICSI for our DS - my DH has a low sperm count and we were told ICSI was our best chance of having a baby. Not our only chance mind (the consultant specifically said he could never say never) but our best. So we had one round and were lucky enough to get pregnant with DS.
When he was 10 months (in January this year) we went back to the clinic, to get the ball rolling on a second round of ICSI. As I was still breastfeeding they said to give that up and wait 2 cycles and get back in touch. So off we went...and then I get pregnant naturally in Feb. It was totally surreal - all those "my hairdresser's sister's neighbour had twins via IVF and then got pregnant naturally with triplets when they were 6 months old" type stories had really annoyed me. We had spent years ttc, and those stories reminded me of when people would say "just relax and it'll happen" or whatever. And now here I was one of those people...
Anyway, unfortunately I miscarried at 7 weeks. It was totally heartbreaking, but we still just felt so lucky to have DS and knew that we'd go down the ICSI route again at some point. But we waited before starting the ICSI ball rolling, as I'm still breastfeeding and didn't want to rush to give it up and wanted to get over the MC properly.
And then amazingly I got pregnant again in June and am now 8+6 and things are looking good with this pregnancy [knocks on wood].
I can honestly say we never in a million years expected to get pregnant naturally and were definitely prepared to not waste time (I'm about to turn 34) and just go down the ICSI route again. My DH's sperm count is still low, so not sure what changed.
Perhaps one option could be to set a deadline, as in start IVF is nothing happens naturally in x months/cycles.
Good luck whatever you decide
