2 Days Late & Negative Test, am I out?

Sarah
So I always have a 25-26 day cycle. Here I am day 27 and no period or any sign of it! Took a couple of hpts but both were negative. This was my first cycle on Clomid with Novarel. Could the meds be causing an extended cycle or could I still be pregnant and my Hcg levels aren't high enough yet? I'm about 12 or 13 dpo based on when I received the trigger shot.
