Advice please

I was diagnosed with pcos a year ago. After finding out I’ve changed my diet and as of this year my period has been regular (30-32 days cycle). I started ttc in August. I am currently 4 days late and I am not experiencing any of my pms symptoms other than sore breast. I did a test but it came back negative. The last time I had sex was 2 weeks ago. However, I am wondering if my period is becoming irregular again as I have also been very stressed lately. Should I schedule an appointment with my gynecologist to make sure everything is okay or should I just wait to see if my period comes ?
