Someone help?

I know this isn’t in the right group but no one responds in the TTC group.. Me and my boyfriend been ttc for a year and half now, and we literally had sex everyday to maybe 4 times a week. We did tests a few months back they said all was good his morphology has to be 4, but was 3.5 that’s it. Everything else was amazing... We’re thinking of trying fertilaid for him because he didn’t get his ex pregnant of 3 years and now she has a kid with someone else only 9 months of them breaking up she got pregnant with someone else. Advice? My doctor said my estrogen and ovaries are great and did a ultrasound and blood work.
