Aduh, sorry to hear you're going through this, chemical pregnancy memang sakit hati. Usually the UPT akan balik negative dalam a few days to a week, depending on how high your HCG levels were when you tested positive; a few of us in the mum chat group went through this and some cleared faster than others. Best thing is to do another test after a few days to confirm, tapi kalau you're worried or bleeding heavily, definitely check with your doctor sebab dia boleh do a blood test untuk track HCG levels lebih accurately. Hang in there, sending you strength
