I spotted light pink off & on for abt 2 days. i took 2 home urine test, one was positive, one was negative. what should i do?

Repeat in 2 days: Urine pregnancy tests are positive when the hcg level is 50. If pregnant hcg should double every 48-72 hrs. If your hcg level was, say, 40, one test may show positive and the other not. In 2-3 days that would become hcg 80 and would be definately positive. So repeat in 2-3 days unless you are having bleeding or pain. Blood pregnancy test measures down to 5 and could be done to sort it out.
