One tip - get some ovulation sticks. My wife and I never realised but the egg is actually only around for a single day - it must be fertilised in those 24 hours. If you have sex after that there is zero chance of conceiving, sperm can hang around so you can conceive with sex a few days before. But outside that really small window you are wasting your time. The actual accurate window is massive guess work - some women are not that regular with ovulation. Ovulation sticks tell you exactly what’s going on - tell you when ovulation is coming, so that’s when you have lots of sex. Before we used them we basically had sex loads (outside this window) which was worse than nothing as it makes you less likely to be going hard in the right window. First time we used the sticks she got pregnant immediately.

We had a friend who had been trying for 8 years to have a kid, told us she was just about giving up and thinking of adoption. We asked if she used the ovulation sticks - “what are they??” We gave her the rest of ours and a couple of months later she was pregnant, now has a baby. So yeah, these things don’t seem to be as well known as they should be, and can be a massive help.

To add to this, home sperm test kits can help rule out the man as well. Some men don't know to avoid vigorous exercise, hot showers, and jacuzzis until they realize how low their sperm counts actually are. (The below kit isn't the only kit. Shop around if this is pertinent to your interests because I don't want to feel like I'm shilling this specific one).

The woman's libido should be really high when she is fertile and men can tell as well; She smells better, and mechanically the sex works better as there is there is more lubrication and it just feels much better.
