I took two pregnancy tests, the second line appeared very faint on both. So I was unsure whether it was a positive or negative. Tried the clear blue digital, and it popped up PREGNANT. But I have had no symptoms what so ever. But lots of cramping, some times dulls and tolerable. Some time only on one side. But some times it's really sharp and feels like it's shooting down my leg. I have an appointment with my doctor tomorrow but I've been a little worried over the past week. Is this something I should be concerned about or is this normal?
