@Bruceytwo I'm sorry your currently testing negative. What I would say is you're not at your official testing date yet, so I wouldn't loose hope completely. I found often it is good to just take a day to feel all the emotions - be pissed off, be angry, scream at the world it isn't fair. Get it out your system.
One of the discussion I had with my partner before we started our fertility journey and we returned to at some points, was just the agreement that, if children were not in our future, that was ok. That I loved my partner and loved our life, and that at the end of the day our life would look different but not lesser without children. I think though that we went into our fertility journey both not feeling like having children was something we must have in our life to be happy or complete us. I started the journey already being ok about it if it didn't work. And we decided that if fertility treatment ever started impacting out relationship negatively we would stop, because we didn't want to sacrifice the relationship we already had that existed for a hypothetical child that didn't. I know many people feel more strongly than that though.
You made a good number of embryos from your first egg collection. Is a second egg collection something you would consider? You could also consider genetically testing your embryos next time if you're wanting to eliminate putting back embryos that aren't going to be viable.
It took us 7 cycles to conceive our DD - we did 4 failed IUIs. I had 2 egg collections. 1st egg collection only 2 embryos - fresh transfer = BFN, FET = chemical pregnancy. 2nd egg collection we did a freeze-all and freeze all (3 frozen). First FET was successful and now my DD. This was all in my early 30s with a normal AMH. AFC everything. I responded poorly to IVF meds, and we'd decided that the second egg collection would be our last.
Sometimes the journey is just a lot more complicated and longer than you think it will be. We went into this thinking a few rounds of IUI would be all we needed.
We've been incredibly fortunate that we transferred 1 frozen embryo in January, which stuck first time and now 20 weeks pregnant with a sibling. There is no logic to why it took 7 tries for my DD, and 1 try for my current pregnancy. It is all just about finding an embryo that is viable.
My last bit of perspective - my BFP came when I stopped testing early, and started deciding that I needed to just get on with my life and couldn't make cycles the focus of my life any more. I applied for a new job that I'd been holding off doing whilst trying to get pregnant. I tried to stop obsessing. And then it happened. I do think there is something about trying to reduce your stress and worry that helps.
Wishing you luck on your journey
