HELP! I'm worried!

This is TMI but I went to the bathroom and the smell of me cm was very fishy smelling! I have never before had that issue. All of a sudden too! Like it wasn't like that this morning. Could this be bad/an infection? Is this normal? I have no other symptoms or irritations, but the smell is very disconcerting! I'm calling my doctor tomorrow but I'm worried an infection could make me misscarry. I'm only 9 weeks today. Please share any advice I would really appreciate it!
