Late period, negative test

Sarah

I’ve had PCOS since before I can remember. I’m currently 33, ttc for over 5 years and on my third round of clomid. I had normal periods for over a year and now I am 9 days late. No symptoms of anything other than loss of appetite. Negative pregnancy test. My mom never had a positive test while pregnant with me. That was a long time ago though. I’m wondering what my next step should be. Any similar stories?
