As ovulation approaches, your cervical mucus changes in amount and consistency. If you don’t notice any signs of ovulation, or your periods are irregular, you should definitely let your doctor know. This information may help your doctor make a diagnosis of infertility.
Two to three days before ovulation you will notice this increase of clear slippery vaginal discharge, during these days you are fertile but, the last day of the vaginal discharge you are most fertile. This is because it is on this last day of discharge or the day after, that ovulation actually occurs. Remember, sperm can live up to five days in the vagina so even if you have not ovulated having intercourse on these days is very beneficial.
