My girlfriend gets only 2 days menstrual period every month. Please I need solution to this problem. It wasn't like that in the beginning.
There is nothing wrong with your girlfriend and what she is going through its perfectly normal.
At first, your periods may be irregular. They may not come every month (roughly 28 days), but more often (every 3 weeks) or less often (every 6 weeks). Don’t worry - this is normal. It can take up to three years for a woman’s period to become regular.
Remember that every woman’s menstrual cycle is different. To figure out how your own cycle works, jot down the first and last days of your period on a calendar for a few months.
Getting your period means that roughly once a month, blood runs out of the vagina. This lasts for about two to seven days.
