@Kitkat247 Reading your post is funny, as we have about the same ages (my DP is turning 38 this year too). We were also at GCRM and used access fertility when we were trying for DD, so very similar boats. You've definitely had a much longer road than us.
Its worth being aware that GCRMs official policy/advice is that you should wean before TTC (their justification is that if you become pregnant your supply is likely to drop which may be stressful for your BFing child). The breastfeeding and IVF facebook group is really helpful for advice if you are still BFing at the point you want to do a cycle in terms of safety of medications, affect on supply etc and also offers support in arguing with clinics that aren't supportive of breastfeeding during treatment to change their stance. There are lots of members that choose either not to inform their clinic of their BFing and/or lie about it if asked directly. We chose to vaguely suggest we had weaned, but also they weren't pushy about asking. I think the only thing that put it on their radar is that I'd previously asked about their policy around BFing and FETs. I don't think they'd ask if you were approaching them after your daughter turns 1.
Everyone's BF journey is really different, so its really hard to predict how your BF relationship will look like come September / October time, but it is worth taking some time to consider how you feel about different options e.g. if you'd do a cycle if she was still BF, if you would delay your cycle if you tried to wean and she wasn't ready etc etc. I chose to keep BF as my DD just isn't ready to wean tbh. Even with no milk, she still very much needs it for emotional and physical comfort (teething 😫). I think as well be prepared for BFing to change when she starts day care / walking / talking / the next regression/developmental leap / tooth coming through / illness as they've been trigger points for us when my DD breastfeeds more.
It may still be possible to have 3 children - I think you really just need to see how it goes TTC a sibling.
I threw up a lot more this pregnancy than I did with DD, and was pretty wiped out between weeks 5-10. I had to rely more on DP to care for DD. I work 4 days a week and have DD by myself on Fridays, and those Fridays were really difficult. Is your daughter walking yet? Has she dropped to 1 nap yet? My DD was walking so made things easier as she'll go pick a book off the shelf / go collect something so I wasn't always having to get up. I also embraced napping when she napped 😂I did however feel like a shit parent during that period, because I wasn't as attentive or present for my DD. That's also the period I've had the worst BFing aversions, which are really horrible to be honest and first time I've really not enjoyed BFing. Everything has got a lot better though after that 12 week point, though its definitely a lot harder to rest this time around.
Its also worth saying that I found TTC this time a lot less all-consuming, simply because there wasn't the time to ruminate about it all. I did the FET with fairly low expectations to be honest, and I didn't do anything during the cycle to try to make it work (no acupuncture or changing diet or any of the things I did trying to influence the result). It some ways its been the least stressful cycle I've ever done. I do think the experience is really different trying for a sibling, as honestly you just have a heck of a lot less time when you've already got a child to care for!
