@strawberrylaces12 I think its really normal to feel more anxious / hesistant during a sibling round around. You know what fertility treatment is like, and pregnancy, and birth if you didn't have a great experience and newborns and all the difficult stuff, and now you're looking at doing it all again but with another still really small human in the mix as well. You don't need to minimise that its a lot, because it is, and you're allowed a moment (or several!) to have all the mixed emotions.
Take it 1 step at a time. You only need to make a decision about each step. Decide on the consultation, then decide to do various tests, etc etc. I think having stored embryos is easier, because a FET is less intensive than an egg collection, and you only need to decide about a FET right now.
Theres 25 months between my 2, and yes there have been challenges, but my kids are about to turn 4 and 2 and they have such a lovely bond and its all been worth it.
Its been hard for me deciding to try for a third again, because things ARE good, and I love my family unit right now. Its hard to try again knowing if it doesn't work I'm going to need to grieve again not having any more. And if it does work, of course theere is going to be hard bits along the way too. But also how amazing to get to see who another little one would be as a person.
You've got this, and hopefully a transfer will work and 2 will become your normal :)
