What do you think?

Okay, so I'm on my 1st round of clomid 100mg, but my second type/try for fertility meds cause the 1st one didn't get me to ovulate. When that happened, my doc had to give me progesterone to trigger my period. I'm currently on CD35 and 3 or 4 days late on my period with BFN tests.

How long should I wait to call my doc again?
