Start on the day this recent period began and count 14 days. That is typically the day you will ovulate (but everyone is different). You'll want to have sex every other day (based on my research that says sperm is at its highest count when there is sex every other day instead of every day) starting now. Other research has shown that the more sex you have (as long as it's once every other day) the higher the odds of pregnancy. If you have sex too often then his body will not be able to reproduce enough sperm and could have blank shooters. I am going to test in 10 days!
It depends on how long your cycle is, your most fertile time is usually in the middle of it
