Had a pos yesterday took?

did you use different tests at different times of the day?? that can influence the results. if you are testing with a less sensitive test then it might just be different. you can test early and actually catch a pregnancy before most women even know they are pregnant. sometimes they end in a very early miscarriage. if i were you i would go get a blood test done. a beta hcg. it will tell you the exact amount of hormone in you system and put your mind at ease. anything above 5 is positive. if your levels are doubling every 2-3 days then it is considered a healthy pregnancy usually. good luck to you!! :)
