Hi Slyvia! Spotting can be harmless, but it can also be a sign of miscarriage. Especially if its accompanied by pain. I would suggest seeing a doctor to be safe. I went to a private o&g clinic everytime i feel anxious over some pain or bleeding. Usually doctor would do a scan to check.. (its an opportunity for me to see my baby 😅). Regardless, please go to a clinic or kkh a&e to check. Otherwise you might constantly feel worried...
Do you have any cramp? Is no severe cramp, likely is just implantation.. but can go see gynae to be sure..
