The HPT will be accurate when its performed 3-4 weeks after intercourse.
It depends on what kind of HPT you used. They are not all the same. Read the instructions. EPT test

No kind of food can affect HPT's, but if you are testing early & drink a lot of water before the test, it could come out a false neg. The water dilutes your urine.
Yes
Could be. You take chances when you take unregulated herbs and substances.
were they 2 different brands of hpt? If so, one is designed to be more sensitive that the other probably. If you are late only by a day or so, I would recommend giving it another week or two before testing again that way you can get a more accurate reading.
19 days after unprotecetd sex a HPT would be able to detect HCG in your urine . All the best!
2 weeks I think
This means you're definitely not pregnant.
