Observing the following signs could help you understand if you are ovulating.
Change in basal body temperature:

This is the lowest temperature recorded, which is usually soon after getting up in the morning. This temperature is usually consistent throughout the cycle, except for when ovulating. During ovulation there is a steep increase in the temperature which could be used as a sign to determine ovulation. To check this temperature, a basal body thermometer is required; which is available here.
Change in cervical mucus:

Cervical mucus is the fluid produced in the cervix which could be taken as a means to identify ovulation. During ovulation the cervical mucus resembles egg white – clear and slippery. In the days soon after menstrual discharge, it is usually absent, followed by cloudy white during follicular development, egg-white during ovulation and cloudy white again post ovulation.
Change in cervical feel and position:

The cervix usually lowers down during menstruation and is on a slightly higher side during ovulation. Also the cervix appears softer, open and wet. The wetness can sometimes be evidently felt.
Tenderness of breasts:

Due to increase in the level of progesterone tenderness of breast could be observed as the one of the symptoms of ovulation.
Apart from these, the usual symptoms could be spotting, abdominal bloating, increased sex drive, increased sense of smell and taste
