that was, a year and a half ago. my periods have been totally normally during this time. This month the same thing happened again.
Again no risk of pregnancy. I can't think of much to add, perhaps there was not fertile mucus at the correct time. (or certainly not a lot)
on both occasions my period arrived 2 weeks after fertility symptoms (which is normal for me) , and with worse cramping than than normal, but nothing else out of the ordinary.
I'm 36, so perhaps its my ageing ovaries, a hormone imbalance I'm open to ideas.
