DeMaz sorry you are in this position too, I can still remember so vividly how hard it was...and so frustrating and painful when you've conceived easily enough first time around!
Yes officially unexplained infertility although a few 'borderline' things, if that makes sense. I had various tests:
- 3 day and 21 day bloods -progesterone levels and FSH all fine
-hysterosalpingogram -tubes clear
- internal scan - uterus fine, ovaries fine but whilst I was never formally diagnosed with PCOS I was found to have significantly more follicles than might be expected for a women of my age (35 at the time).
-DH had the usual SA and was found to have poor morphology but an exceptionally high sperm count, so the poor morphology was kind of cancelled out by the sheer number of sperm in the analysis.
So nothing major discovered but a couple of not-quite-textbook-perfect issues picked up which may well have had an impact on our struggles to conceive.
We went through phases of trying alternative therapies (acupuncture, reflexology), taking stacks of vitamins and supplements, and cutting things out of our diets (alcohol, caffeine, sugar etc). Not sure any of those really made much difference tbh but at least we felt we were doing something positive at the time!
I was 32 when we had the super-easy conception of DS1, nearly 34 when we started trying for a sibling, 37 when we finally went through IVF and were blessed with DS2, and just 40 when we conceived DS3 naturally, if that helps anyone worried about age-related fertility concerns...
Oh and on the age gap between children thing, and worries about it becoming too big and so on...I used to obsess about this, literally working out each month what our age gap would be (down to the week) if I were to conceive this time. I desperately wanted a 2 year gap, 3 year maximum, and got 5. It's not what we planned/hoped for, but actually, it's lovely. The older two have a great (if noisy!) relationship. DS2 is currently rather unimpressed with baby brother, but DS1 (now nearly 9) is transparently besotted with him. DS1 was an only child for over 5 years but we've never had any major jealousy issues. There are so many plusses - not least that with a bigger gap, you have the time and energy to enjoy the second baby so much more. I've been able to give solid chunks of undivided attention to the younger two that just wouldn't have been possible with my longed-for two year gap. And I can honestly say that I enjoyed DS2's babyhood just as much as I did DS1's, and I'm now enjoying DS3 just as much too, and I don't think I'd have experienced that same level of enjoyment and sheer delight in doing the baby thing again had their conceptions happened quickly and easily.
I hope that helps, although I know that when you are going through this it feels like it will never ever happen. But it can happen and hopefully it will for you too.
Lots and lots of good luck to everyone on the thread.
