New to glow

Hey guys we are new to glow just trying to increase our chances of conceiving! A friend told me about the app just checking it out. So far I love the calendar helps me keep everything logged and I can track my cycle. Just a little back story me and my husband been together five years, he has a child from a previous relationship and I have a child as well from a previous relationship. We just think it’s time we have one more together. The crazy thing is we have been together five years four of which we never used birth control or condoms. We did get pregnant one time but unfortunately I misscarried at 20 weeks. Since that issue we have not been able to conceive. But I have to say My first child was a happy accident at only 16 years old. So now that I’m actually trying it’s been very hard. I also always thought you ovulate three days after your period which now I found out is wrong !! Any comments please help meeee !!!!!
