You dont think you are pregnant and you have never had a pregnancy before but you have a brown line on your stomach and your period is a week late so farDoesthis mean you are pregnant or is it normal?

If you are only 1 week late the mark on your stomach is probably unrelated. The only brown lines I have ever heard of appearing on pregnant women is stretch marks which wouldn't occur until you started showing (not for another month at least!) The mark could be an unrelated stretch mark from putting on some weight or something completely different. If it is sore check with your doctor.

As for the pregnancy, either wait a little longer, get an at-home test, or see your doctor. There is a possibility that you can miss your period entirely and not be pregnant especially if your periods are usually light, but don't count on it.

Other things that may cause a missed period include extreme stress, diet, or exercise. Take it easy for a few days and try to stay calm. If you have been dieting, be sure you are getting enough calories and nutrients for your body to function. If you don't start your period in another 3 days to a week you are probably pregnant. Congrats!
