So confused...

This is out third month ttc. AF was on 10/24-10/28. Been using the clear blue easy fertility monitor and on CD10 it asked for a test and it was at peak (which was early from prior months) so we BD Sunday and CD11 Monday. Then tuesday, Wednesday and Thursday I had some light brown spotting. Today I've had moderate amount of bleeding but no cramps. I always have cramps with AF. So I'm so confused is this AF super early, never been irregular, been off bc for four months. Should I go see my doc? Getting discouraged.  Help!! Any advice appreciated.
