they should be very accurate if you followed all of the instructions for the test and waited long enough to take it. If you are unsure, take another to see if the results are the same, if yes, than I would definately not worry about it.

Home pregnancy tests are supposed to be pretty accurate. Since you said you feel antsy about it, just make an appointment with your doctor and they can schedule you for a blood test. These tests are extremely accurate and can be taken the first week of conception. They are so sensitive that when they measure the hcg levels (pregnancy hormones) in your blood they can tell you how far along you are! You may want to do that, or just take a different hpt. Good luck and I hope you get the answer you want!
