Have light but bright red vaginal blood 2 weeks before period. had sex two days ago. had a normal smear in march and normal pelvic ultrasound in july?

Question vague but: Many women have occasional variation of their mucus discharge, some spotting between periods, a heavier period, a lighter period, a longer or shorter period, or even a missed period. Having one or two of these symptoms doesn’t necessarily mean there is a medical problem, but a visit to one’s primary care or Ob-Gyn doctor is a good idea if symptoms are persistent, recurring, or worrisome.
