LOL LexiRexi, you will not die from that

. It might be scary and uncomfortable, but not fatal.
If you are bleeding heavy, you should take an iron supplement to replace the iron you lose when you menstruate. Iron help with red blood cells and red blood cells are responsible for carrying the oxygen in your body. If you lose a lot of iron, you will feel weak and tired and may look pale.
Are you bleeding or just spotting? You should talk to your mom about it. If it does not stop soon, you will have to see your doctor so that he/she can take a look to make sure everything is ok.
Best of luck!
