Aw mama, that brown spotting can happen talaga kasi the body is still clearing out the blood from the hemorrhage, a few of us moms who had SCH experienced the same thing, and it took a few more weeks pa before it completely stopped even with bedrest and meds. Since baby is okay and you're already on Duphaston, that's good, but honestly I'd check in with your OB again if the spotting is still going on after 13 days, just para ma-confirm if everything is progressing as expected or kung may changes na need sa treatment. Sending you strength, mama, this is stressful pero marami sa atin ang nalagpasan ito!
