WHAT DOES THIS MEAN, STILL DOES NOT LEAVE THAT THAT APPEARS WITH A CLEAR OF THE EGG, BECAUSE I WANT TO FULLY ENGAGE, HELP ME IF IT WAS NOT ON THE SAME DAY TELL ME WHAT A BETTER DAY OR I HAVE TO WAIT TO SEE.
Expert answer:

Fertile days are between the eleventh and seventeenth days of the menstrual cycle, with the first day of menstruation being the first day of the cycle. Then had a relationship within your fertile period, which is very little, but sometimes enough to get pregnant. Co related to your discharge: it is a vaginal discharge, usually due to a vaginal infection.
