help me decide on next steps, need advice and personal experiences

My husband and i have been trying for a baby for about a year and half (most cycles). were coming up on about 9 months post mmc. i went back this month to the fertility clinic and got an hsg,sis, and endo biopsy all came back good and clear. my husband had an SA done about 9 months ago and came back mostly normal, good parameters with slightly lower volume and morphology (2%). my fertility doctor had monitored my follicle growth and said to time intercourse this cycle, and if it doesnt work we can start being a bit more aggressive.

I already ovulate on my own (typically around cycle day 14/15) with regular cycles every 27-28 days. Would it make sense to go on letrozole next cycle with trigger shot and IUI? Although my husbands sperm is normal, i worry there might be some dna fragmentation so i was going to ask about the ZYmot method. He's been on many supplements to help with this potential issue.

Is doing all three as next steps too aggressive? any success stories from doing all three in a cycle with regular ovulation and no MFI?

The ttc journey is sort of also putting a strain on our relationship and things feel forced, and I'm pretty much always down which also makes it hard to feel connected during this time.

I'm not gonna lie, this whole ttc journey, although i have a loving and supportive husband has also caused some distance and disconnection lately.

Thank you so much.
