Light spotting

Jennifer
Has anyone had any light spotting? I just found out that I'm pregnant (edd is late April). I had a faint line BFP on Friday and then this morning I took another test to see if it's darker. It wasn't. It was a little bit lighter. Then this afternoon I had a little light pink, almost yellow spotting. It's been about an hour and hasn't gotten any heavier. Wondering if this is a chemical pregnancy. Anyone else have light spotting? I did with my first pregnancy, but I was farther along then and it didn't last long. Just hoping this is all that I get and it doesn't keep up. Thoughts?
