Is it a sign of pregnancy if you start your period late and the bottom of your stomach is still cramping when you stop your period?

YES! I had a friend that was pregnant and didn't know the whole time. HERE'S THE STORY We were watching t.v. and my friend started cramping so she went and took a nap. Two hours later she came down stairs to tell me she peed on herself. Well a couple hours later she couldn't even walk she was in so much pain. I ended up taking her to the doctor and she was nine cm. dilated. She didn't know she was pregnant because she never missed her period. Her daughter is now a healthy 2 1/2 years old. It's better safe than sorry to go to the doctor than not to know so you could enjoy the pregnancy.
