No problem, I can see why your situation seems confusing, mine did for many years as well, my body is an unusual one so at two other stages earlier on my thyroid also looked like it was normal, but then by chance on a routine blood test it was 8 times over active, I was very hyper, talking fast, full of anxiety and it was an over active thyroid, so look up symptoms of over active and under active and if you ever feel like those then go straight for another blood test, also get the antibody test for the thyroid as this is important.
Autoimmune testing might be worth a go and maybe a more details DNA fragmentation on your partners sperm, also I would suggest getting another ovulation , follicle tracking done, again everything looked normal on paper for me and even the consultants where conflicting in their advise to me.. but it looked like I ovulate but not perfectly, so my bloods show up as though I do.... they couldn't figure out if I had partially ovulated and in that case you would need a trigger shot, to guarantee ovulation and like what the girl said, clomid or letrozole would be what I would ask for next, that is if you don't want to go to all the other expense.
Letrozole for me makes me feel unwell, but I guess whatever works, it will give you a better chance. Recently a girl who has similar history to mine got pregnant with taking 9 letrozole, but again a consultant would advise you on that as I'm not a doctor... but am happy to help anyone.
Napro might be worth giving a chance, you could be only with them a short amount of time, for me I'm heading towards 40 so need to move to IVF.
Basically another thing you could do and one Napro will advise is cut out wheat & Dairy, up your vitamin dosages, Vit D, Omega 3, Vit B for women and men. Cut down on drink, and my tip buy yourself a little fertility bracelet. You can buy ones on Etsy - I have so many issues the girl had to Tailor make one for me, all in all under €40.00 and I am looking forward to getting it.
