Are you trying to get pregnant ?  These signs indicate that you are fertile now.

Heightened sense of smell : A woman’s sense of smell becomes more  sensitive in the latter half of a normal menstrual cycle as she  approaches  ovulation.  Women in the fertile phase are more attracted to the male pheromone androstenone hormone.

Increased sex drive : Right around the time you ovulate, your lips may become fuller due to increased estrogen.  Your pupils also become dilated and skin feels softer.

Changes in consistency of cervical mucus : As you near ovulation,  your body produces more estrogen, causing your cervical mucus to become stretchy and clear like egg whites.Your cervix also changes and  will become higher , softer and more open during ovulation.

Changes in basal body temperature : As you get closer to ovulation, you may have a slight decline in body temperature. However this is followed by a sharp increase after ovulation. This increase in temperature is a sign that ovulation has just occurred.

Breasts become more sensitive : The time of the month when your breast are sensitive and nipples become tender  is due to a rush of hormones entering the body right before and after ovulation.
