If the first one blood pregnancy test said positive and the second one said negative can I be pregnant? Should I take another blood test?

Yes and yes. You can get positive followed by negative if the test was done improperly or if the pregnancy failed for any reason. Should repeat the test in a few days. The chemical detected in the pregnancy test doubles every 2 days or so should be unmistakeable in another few.

The blood one. is more reliable. although it would depend on the timing of the tests.
