Hi u/leag63,

Great question. For many couples the best way to start trying is to make sure you are timing things with the woman's menstrual cycle. The easiest way is to plan to time sex every 2-3 days from when her period ends until she expects her next period. If her periods are unpredictable, this is reason to see a doctor rather than try for too long on your own. If she is over 35 it is a good idea to do some fertility tests even if you are planning to try naturally just to make sure all is well.

The basic tests are semen analysis, uterus and tube test (like an HSG), and ovarian reserve testing (such as AMH and ultrasound).

The most common thing people may not know is when to time sex especially when a woman's period is irregular.
