Can your period cause cold-like symptoms like scratchy throat and a stuffy nose? i've noticed those things tend to happen to me during every period....

Could be: One way to ascertain may be by limiting your periods. Your doctor can prescribe a pill that can limit your period to once a year or so. Have a healthy diet, exercise 30 minutes/day, drink plenty of water, have safe sex, no tobacco alcohol weed or street drugs. For nutrition: http://www.choosemyplate.gov/. Get HPV vaccine. Wish you good health!
