Mama, I really think you should see your doctor or go to the clinic as soon as you can para ma-check properly, they can tell you for sure what's happening. Implantation bleeding is tricky kasi it can look like different things for different people, at marami pang ibang reasons bakit may bleeding, kaya hindi ko dapat mag-guess sa ganitong sensitive situation. Better safe than sorry talaga, lalo na kung first time mo ito experience. Let me know after you see the doc, ha? Hugs!
