MrsH14 I am pleased this is being of some use.
I think you need to hold on to this.. "I do think I would kick myself years down the line if I didn't give IVF a go but I'm not sure I can put myself through it knowing that it might not work anyway."
Re "I'm not the most patient person and a little bit sick and tired of feeling like our future is in the hands of people that don't really care how the waiting is affecting us."
Totally agree with tldr re "I completely understand that, but don't think adopting will make that any different. Perhaps you need to just accept that whatever route you choose, it's essentially going to be a giant PITA on someone else's timetable."
I found MANY IUI attempts (one successful with just one egg) and one IVF attempt and two IVF attempts with donor eggs and one IVF attempts with frozen embryos made with donor eggs to be OK, stressful but OK. I found adoption OK but stressful (especially matching). And our son joined us two years ago via adoption when our birth dd was 9.
All quite stressful BUT I would not be without either of my adorable children.
The medical profession for IVF etc did basically treat us like a customer, most of the time (well ours did as we were, we were paying). We were on a medical time table. Social services treated us well, with respect, but we were definitely on their time table.
We were required to wait 6 months before starting adoption after IVF. I have heard different periods of time in different places. Our choice to go down the adoption route came at the end of a long time of IVF so we could say we were genuinely through with IVF.
IVF is not just about having a biological or genetic link with your child. I had treatment with donor eggs, there would have been a biological link, e.g. my body, but not a genetic one. Some choose IVF with donor eggs or sperm, even though there may not be a genetic link because the woman wants to experience pregnancy and birth, or because the couple want to know about all the things that have influenced their child from conception onwards.
Adoption can work out extremely well and can be a great choice, but I would really not down play the need some people have to experience pregnancy or birth, or to have a biological or genetic link to their child or simply to not parent a child who has had a troubled start in life. It is not a bad thing to decide to decide for IVF, if it feels right for you. With either adoption or IVF there are no guarantees, I know people who have had IVF and it never worked. I know people who have given up on the process of adoption.
Hope you will find some peace in all this.
