TTC UNEXPLAINED INFERTILITY

hi all, so short run down - my husband and I have been TTC For 2 years now- we have had all the checks and everything is fine with both of us- we have a miscarriage in march this year after falling naturally and have not been able to fall again since. My fertility dr has put me on letrozole to 'ramp up' my ovulation since and I have just had a laproscopy last week and our results came back perfect along with my tubes having dye studies that flowed through fine also. Has anyone had success with their 1st <a href="https://glowing.com/glow-fertility-program">IUI</a>? Or any other suggestions for us? I have just tracked ovulation through dates and CM - does anyone also track through temps?
