### output:

Hallow Dear, Pregnancy tests are based on the raised titles of hormone Chat Doctor in the body. The title starts falling down after abortion process and roughly after about 8-10 days it becomes undetectable in the urine. Therefore, the pregnancy test becomes negative about 8-10 days after abortion. Positive pregnancy test 9 weeks after miscarriage cannot be attributed to that pregnancy. You have to consider following possibilities:1. You may be freshly pregnant again. Ultrasonography after about a week can confirm the diagnosis. 2. Failed abortion last time. This also will be clear after ultrasonography. However, you had menses 5 weeks ago, hence this possibility can be ruled out. 3. You could have developed choriocarcinoma or molar neoplastic disease. You have to report to Gynecologist to get quantitative estimation of the Chat Doctor in your body. If indicated, you may have to undergo curetting for biopsy of the tissue inside the uterine cavity. Ultrasonography is helpful in detecting or suspecting these lesions. However, this condition causes alarming bleeding which you do not have. Still, it is better to rule it out. Better to err on safer side. Choriocarcinoma can be completely cured with medicines if diagnosed and treated in time. I hope this gives you guidance for next step.
