loaf too dense

Hi TFL,

I don't know why my breads are doughy in the center, and heavy after baking. I've had it happen on 2-3 different recipes.

After a few hours it doesn't seem doughy, but still has a heavy feel to it.

I started a sourdough starter three days ago.

I used a quarter cup of whole wheat flour and a quarter cup of water (half cup of starter now).

I left it for eight hours and added another quarter cup of whole wheat flour and water (one cup of starter now).
