I can totally relate to time going so slowly.
I have been TTC #2 since Sep 2011. Every 2ww was forever. I tried to be practical booking appts to try to get answers (I guess the phase where you are now at) and they all took forever to come around. Here I am, 8 IVF cycles later, and still impatiently waiting for my BFP.
Personally, I wouldn't at all stress about the success rates of ICSI where there are male issues and ovulation issues. I couldn't imagine there are statistics for male + ovulation issues. The fact that you don't ovulate has nothing to do with your IVF cycle. The hormone injections will completely control your cycle to get your producing eggs. In fact, with with PCOS who don't naturally ovulate, often have larger ovaries and more eggs because they aren't being ovulated every month and hence, these women are at risk of producing too many eggs for IVF or ICSI. So your lack of ovulation will not hinder your ICSI in any way. The number one factor that affects eggs is age.
It's up to you to decide if Clomid is right for you. But we had tried to conceive naturally for 6 months before the first SA revealed DH's sperm was 98% abnormal morphology. So it didn't happen for us even with those 2% normal sperm and me ovulating naturally for 6 months. (It has since gone to 100% abnormal and not changed).
We then actually did Clomid ourselves but to no avail. It was quite stressful as you have no idea what is going on and no idea where things went wrong when each cycle failed. But I have learned a lot from our ICSI because you are monitored with blood test and ultrasounds up until egg retrieval. Then everything happens in the petri dish. So you can see exactly where things are failing and work to improve them for future cycles.
I discovered I didn't make many eggs and have since taken Aspirin in the lead up to my IVF cycle to double my egg count. My first ICSI, my embryo didn't even make it to day 2. I am vegetarian so started trying to find more vegetarian sources of protein. My next IVF, the embryos made it to day 2 transfer but weren't great quality. I then gave up vegetarianism (the thngs we do for a baby!) and chowed down fish and chicken. My next IVF produced an embryo that made it to day 2 and was top quality. (Still a BFN cycle but I could see improvement. I won't go on with all my IVF details but as you can see, it really gives an insight into what's going on and there are practical things you can do. So from my experience, I would move straight to ICSI rather than Clomid. Albeit, I know ICSI is expensive and I am working between ICSI cycles just to fund the next cycle. It's horrible that our desire to have a baby has to be determined by the size of our wallets.
As for the immunes testing, I have researched it, but from what I've read, it seems these women generally have repeated miscarriages. The fact that I got DS tends to show me that I have no immune issues. Perhaps Silverstars can suggest if this is worthwhile investigating for you since she has been through it. And if she thinks it is worthwhile for us, I am happy to be informed.
I too want another child for my DS more than for me - that doesn't sound terrible at all. Nothing wrong with loving your daughter and wanting the best for her. Tips on how to accept our situation... hmm... I have absolutely none there! Here I am about to embark on ICSI cycle number 9 so I guess that tells you that I am unable to accept the cards I've been dealt! The one thing that I have found is that as I read your posts, it sounds like exactly how I would have felt 2-3 years ago. Somehow, after 8 cycles of ICSI, I am just now starting to get over all of this and feeling like perhaps it might be okay if I forget it and move on. But this is me speaking now with fresh hope as I start taking tablets to prepare for my next ICSI cycle in 17 days. I might be completely different as the cycle ramps up and I am desperate for it to succeed.
I am glad that chatting here has helped. I too find this a great source of support. So please feel free to type away and let it out. Happy to listen. Also makes me feel like I am not alone so thank you.
