Should I go to my OBGYN?

Need advice on whether or not I should make an appointment with my OBGYN. My husband I have been TTC for 6 months but I don't have a normal cycle and he has a varicocele. My cycle will be between 35 and 40 days but this month I am at 42 days with a BFN. And I started cramping today. My OPKs every month have been close to the same darkness in the lines but never darker. Also I have only had egg white CM for 2 months. With all of this is it too early for me to go to my OBGYN or should I make the appointment?
