Hello, Thanks for letting us know your health concern. If you are sexually active and not using any contraception, this spotting could mean an early implantation bleed. To clarify, you can go for the assessment of the serum beta-hCG titres now. Else, this spotting could mean an early onset of your next natural period and premenstrual symptom. This can happen with transient hormone disruptions which can occur with sudden weight changes, stress, infections etc. A sonogram of the pelvis after another week could give more information. Further management can be planned accordingly. Hope this helps.
