All the symptoms of a period without the bleeding?

I've had a perfectly regular cycle since I first got my period. This month though, everything was on time (fertile window, pms) except the day I was supposed to get my period, I had all the symptoms but no bleeding, not even spotting. I'm three days into what should have been my period with symtoms (except cramps) and still not a trace of blood. It may be because I've been under a lot of stress lately, or my existing health issues. But I was just wondering if anyone experienced this before, and was anything wrong? Also, I have no idea whether or not to log that I started my period.
