Late period

Please no judgment...

I was supposed to start my period three days ago, and still haven’t. The day before I was supposed to “start” I had unprotected sex, but he didn’t cum. That was the first time I had sex in a long time and had my last period around 30 days ago. I’ve been struggling with heavy and painful periods, so on Friday they did a full blood panel for my thyroid. I have also been extremely stressed as I have big life changes. Having sex one day before my period couldn’t have caused me to miss this one, right?

Thank you for your help and kindness.
