Sayang, since your doc dah check you dan bagi ubat, follow the instructions carefully, rest, take the medication on time, dan jangan delay kalau ada changes ye. A few of us mum friends pernah experience spotting during pregnancy and doc's advice is the best guide, some improve, some need follow-up scans. Jangan risau sangat, tapi if it gets heavier or you feel anything else (cramping, dizziness), go back to the clinic or A&E okay. You're doing the right thing by resting. Take care of yourself!
