I got my period last night but it's light and i'm freaking out. can sexual activity lighten my perid? what do you think?

Sex won't lighten it: A doctor can check to see if there is a medical issue, if a woman has mild menstrual-related symptoms. Many women have some variation of mucus discharge, of periods, or a missed period on occasion. Some women feel normal after a few days, but others have bothersome symptoms and follow-up with a doctor. A urine pregnancy test is accurate if done correctly, after missing a period or 3 wks after sex.
