Ay sis, I'm so sorry you're going through this A pregnancy test can usually show negative within a few days to a week or two after a miscarriage, depending on your hCG levels, pero honestly, every body is different, kaya mas better na check with your OB para malaman mo exactly kung kailan ka fully cleared and what to expect next. One of my close friends had the same experience, at dala niya agad sa doctor para ma-confirm at ma-guide siya properly, kasi importante na sigurado ka na okay ang iyong health. Sending you strength, sis, alam ko it's a tough time.
