No period since June but spotting for 2 months with MAJOR PMS symptoms

Hi All 8-| I have always had very irregular cycles, but the older I get the worse they are (30 y/o). I have not had an actual period since early June however I have been spotting (quite heavy at times) for the last 2 months or so (esp with a bowel movement). I quite often feel like vomiting, mirganes, SERIOUS water retention, weight gain, moodiness, my body is producing milk even though I am not prego (never was nor will be), cramps, lower back pain etc etc. Has ANYONE else experienced this before????

I have an appt with an endocrinologist in Oct, but this is really getting out of hands now.... please help[/img]
