The issue is egg quality. You may be ovulating every month like normal but your FSH level indicated diminished quality. AMH will be a better indicator of quality but the elevated FSH is what's likely causing it to take longer to conceive just like it did before.
I don't think swaying and what you're dealing with mix. You should be as healthy as possible and DTD every other day around ovulation to try and catch the one good egg.
I took DHEA to help with quality. It helped me. I had bad pretesting too. DHEA helped me. Here is the link to the info about it -
