Advice ttc?

So me and my boyfriend been trying for over a year now, had blood work and ultrasound done and everything was above normal even my estrogen and hormone levels amazing and my ovaries. My boyfriend had sperm analysis done, and his was above normal as well. Only thing that was off was his morphology but it was 3.5 instead of 4. Which is barely low. I’m so frustrated we’ve used preseed. Maybe because we have intercourse everyday ruins it, and this app is always wrong on my period, so must be wrong on my ovulation as well... I want to try pills/ vitamins for us now. Anyone heard of anything that works? We’re thinking Fertilaid for him and female prenatal vitamins for me. Advice? Anyone know any good ones that help work? So frustrating 😭😭😭😭😭
