Tips 4 Trying 2 Conceive Naturally

I'm almost 37 years old & I've never been pregnant. I knew I always wanted kids but I was in a relationship with another woman for 14 yrs but I ended up with a man that I feel is my soul mate and we wanna have a child together. Now he is 50 years old and he has 2 kids and both kids he has he got the mother of the kids pregnant on the first try, both times. But that was also when he was in his 20s. We just decided that we were going to try to conceive naturally so last month was our first try but unfortunately I got my period today. I'm pretty good at reading my body and what's going on with it at the time and now using this app along with reading my body and I also have ovulation test strips, I'm hoping I'll have better luck next month. I'd love if anyone has any suggestions or help. Thanks
