increase in BM at 10 weeks?

A little TMI depending on your level of pregnancy share, but I went from being constipated Thursday and Friday to an increase in BM Sunday and today. Is this normal? I'm 10 weeks along. I haven't exactly had a healthy day- chik fil a with a chocolate milkshake, strawberries, an apple and grilled cheese for dinner- but I usually eat quite a bit of fruit every day. I was pretty regular before pregnancy so wasn't sure if I am getting back to "normal". Anyone else have experience with this?
