###Human: Getting abdominal pain twice in every month. One during the first day of the period and then on the 9th day of my period. ###Assistant: Hi. Many individuals experience such pain. The period day pain is dysmenorrhoea (pain due to menses). The mid-cycle pain is ovulation pain called as Mittelschmerz in our term, due to the release of the egg. This usually indicates the ovulatory cycle.
