I took 3 tests EPT brand the first was positive the last 2 were negative am I pregnant please respond ?

Unlikely. You may well have been pregnant and had a very early miscarriage. My suggestion would be to call your obgyn and have him/her order a blood-based, or serum, pregnancy test. It will confirm whether you are pregnant or not, but won't necessarily confirm whether the pregnancy is healthy until you do a second such test and see an appropriate rise in hcg, the hormone that is measured in these tests.
