yes oh my gosh! This has been me lately over the last almost 10 months now! It would come at the end of the month, then each new month, it would start coming earlier and earlier and one month it didn't come at all. Like in February it came around the 26th of the month, now here in November, it came on the 4th! I really don't know the rhyme or reason. The last time this happened to me, I had fibroids that they said were messing with everything. I also have PCOS so I don't really know if that could be the culprit as well. But it is so frustrating and definitely hard to plan each month because it really just comes whenever it feels like it! Have you talked to your doctor about this!? -Kimberli (advocate)
