For the past year or so I have been noticing some strange changes to my menstrual cycle. Usually I get my menses regularly on a 28-29 day cycle. However in October last year I seemed to have missed my period and I had also experienced similar symptoms to pregnancy that month. Some of the symptoms included; serve fatigue, slight spotting, dizziness, lower back pain, frequent urge to urinate, sore breasts and irregular bowel movements. I am not currently on the pill or any medication. I exercise regularly and eat a very well balanced diet. I also sleep 8 hours a night but when I awake it feels like I didn't sleep at all.

I was tested for thyroid, hormonal levels, PCOS and urinary tract infection, did a pelvic examination and was also tested for pregnancy. All tests came back clear which was good but I am now experiencing the same problem again this month. This time the symptoms only include serve fatigue, missed period, urge to urinate, hair falling out and lower back pain. I am currently 3 days overdue and starting to worry a little about what is going on. Do you think it could possibly be a once of irregularity or could the previous results of the tests possible be inaccurate ? I also noticed that I did not ovulate this month with no PMS symptoms to follow - I usually get PMS symptoms prior to my menses. I don't have painful periods but find that I am often rushing to the toilet after meals.
