Girls have their 28 day cycle of shedding their uterine walls when their ovulating stage wasn't given a chance to be fertilized.
During your period, you should definitely avoid the following.
- Staying up all night
- Working over time
- Skipping meals
- Doing Physical Workload
- Drinking Cold Beverages
- Making Love (unprotected) During your cycle, you are extremely prone to infections due to the fluctuations of your hormones. You uterus is already under a lot of stress so do not stress it out even more by doing those. Make sure to give yourself some rest and do not put pressure on your abdominal area.
