Hi. I Took Cytotec On A Three Weeks Pregnancy. I

Hi. I took cytotec on a three weeks pregnancy. I bleed for two days. A week later I did test and it still shows positive, after which i took 4 Misiprosole tablet, the next day i went to do scan. I was told there was an incomplete miscarriage but I don't have to worry and it is very small. I can send a copy of the scan if you want to see it. Today I decided to do a urine test at home and it's still showing positive. If the pregnancy is still there, it should be five weeks but if its not there why is my period delaying and why is the test showing positive.
Am confused please clarify me
