Okay, I had my last period on January 25 and I got a depo shot on February 1 and I took a pregnancy test on the 21 and it was positive and on February 25 I took a blood test and it was negative and also the next day I took another test and it came up positive now I should let you that this is not my first time getting pregnant on depo

If you did a blood test at the doctor, and it was "not pregnant" I would tend to believe that, and suspect that you may have some error in your testing with a home test.

I would confirm the blood test with your doctor.

Agreed, have another blood test done to confirm one way or another. Ask about it being a quantitative test that will test for the level of hcg... a hormone associated with pregnancy.

Did you follow the directions on the home tests? One common mistake is reading the results after the time frame stated on the directions. On some tests you can have what may look like a positive show up later, but it would not be considered accurate.
