Ok so my period was 4 days late and yesterday I had a light brown flow. Today, it's down to really light spotting that's light brown and pink. I literally *just* got a BFN 2 days ago, but my periods have never been like this. My normal period is heavy for 2 days, trails off next 2 days, and last day is heaviest. So... Should I take another test? Call my doctor?

This is my first time TTC and I have no clue what I'm doing and I could use the help. Thanks everyone!
