When you use the restroom, CHECK THE TISSUE every time. After a period
, you should be dry (no CM present) which means
you are not fertile at that time. As your body prepares for ovulation, you'll notice some CM (yellowish/cloudy/milky/white, gummy/tacky/sticky, etc.). You're considered "fertile" at this time. Sperm can live up to 3 days in the vagina, so you really only need to BD (baby dance=sex) every other day, that way your husband has time to create more sperm.
