Took home pregnancy test. control like was very dark and the test line was very light. am i pregnant?

If uncertain: go ahead and repeat test. I don't know the particular product that you used.

Maybe, but...: A faint positive line on a urine pregnancy test is still positive, but the concentration of HCG in the urine is not high enough to create a strongly positive line. If pregnant, the line should be strongly colored a several days later. One can test again in 5 days (but wait longer until 3 weeks after sex, if 5 days from now it still hasn't been 3 weeks after sex).
