The first time I had mine, was really odd. I woke up in the middle of the night because I had to go to the washroom. Then I notice it. I was really scared. So, I found a pad, put it on, and went back to bed. Then I went to school. I change my pad there, and when I got home it stop. So, months later, I got it again. for only 2 days. Then 3 months later, I got it again, for only a day. If you are wondering, I though it was really odd, so I put a red dot on my calendar when I got it.
So, now, years later. I don't get mine every month, and when I do get it, its only for 2-4 days. My longest one, was for 6 days. I never got cramps or anything. I started when I 14.
Don't worry babypigggy, its different for all of us. It might not be that bad for you. You are just going to have to wait. Some days, you wish the whole world will die, and other days, your fine. It also depends how your family is with you. My brother piss me off, and lets say he is lucky to be alive.
