There are so many questions I have

Dani

I had a miscarriage back in may. We have been trying to conceive for about 3 months now. And it’s starting to get a little discouraging. I’ve been taking prenatal pills, been eating healthier and tracking my ovulation on 3 apps. I had sex with my husband 3 days before my ovulation day. I did research and it says that sperm lives up to 5 days and waits for the egg. So I’m just wondering why its not happening for me. Any thoughts?
