I took abortion pills a month before and yesterday I did my blood test and test says I am still pregnant. I am bleeding too. How is this possible?

Tests and follow up. The pregnancy test detects hCG hormone. This can take weeks to completely clear. Depending on the type of test they're checking, trace amounts may show up. Your doc can check a quantitative (number) and recheck in several days to ensure levels are decreasing. Also f/u so they can confirm that there are no residual components of your pregnancy. They will want to check this if you're still bleeding.
