I also had my very light brown spotting at my 6-7 weeks AOG. Accdng.to my OB i have a minimal subchorionic hemmorage at eto po caused ng spotting ko. But upon checking the baby ok nman po ang heart beat ni baby. Iwasan nlang po ang gumalaw galaw at take all the meds na bigay ng OB po ninyo.
Any colored spotting po is not normal but if you already consulted your doctor and recommended some meds then probably that's the best for you to do. Just don't further worry and baka mas ikasama mo pa.
