No period yet??? If not go get blood drawn!!
It's common to get a false negative, it's never common to get a false positive. It's almost impossible to get a false positive
I would wait another week and take another pregnancy test.
That happened to me too so no worries! I took 4 pregnancy tests and got 2 positives and 2 negatives. After doing tons and tons of research I've came to the conclusion that a $1 pregnancy test is just as good as a $100 pregnancy test. Get some blood work done and I bet you're pregnant (:
If you're newly pregnant (like VERY early) the cheap test might not be strong enough to pick up on the hcg in your system. Like said above, it's very hard to get a false positive on a pregnancy test.
Did you take the test with your first morning pee? If not then your pee could have been deluded and caused the negative. But I would suggest getting the blood test to know for sure
