I had a surgical abortion 6week ago and i took a pregnancy test today and its still positive.is ir normal?

Yes.: Hormone levels decrease by about 1/2 every 48 hours. Because they are so very high during the first trimester, and the tests available today are so sensitive, it is certainly possible to have a positive screen for as long as 60 days. If you engaged in unprotected sex, you could be pregnant again, so you should get quantitative blood testing to confirm what is going on.
