Are you sure of that measurement, hun? 2 tablespoons is quite a lot of blood...That is about half an average period total loss. So, very significant. How did you measure it? Often it can look like there is heaps when it really isn't that much in reality. Is it constantly bleeding or has it stopped?
How far along are you? If you are sure of that measurement, I would go and see the doctor if I was more than 6 weeks.
