Simple Question: Please, this is a simple question and does not need to be asked over and over. You are not pregnant. The test was done well past any date that would be doubtful.

Yes: Had you become pregnant from sex five weeks ago, a blood test for pregnancy would be positive. A negative test will rule out pregnancy, if the test is done correctly.

Probably: A serum pregnancy rarely gives false results. Three weeks after sex with a negative serum pregnancy test is probably accurate.

You are not pregnant: Yes. Of course. A negative at that point is negative.
