Ovaboost & Myo Inositol- I'm trying it, ttc

I'm 40 years old next month, my husband just turned 30, & ttc for 8 failed months after losing our daughter at 5 months pregnant last year due to an infected placenta. I delivered her naturally as my water broke but did end up with a D&C due to postpartum hemorrhage. We had no issues conceiving our now 2 1/2 year old daughter or the one we lost. I ran across these products and thought its worth a try. Has anyone else tried these? I also got my husband some of the mens supplements. Had an ultrasound and blood work done but the no phone call means "no news" and nothing showed abnormal so its a mystery as of now why nothing is happening 😔 My cycles are normal, ovulation sticks show lh surge every month consistently on day 14 etc. So if anyone has suggestions, insight, stories we all learn from each other! I'll definitely be following up if anything happens. We've already tried preseed for 4 months too.
