I'm on day 9 and while at work noticed I felt the "period back ache" start to come on. It was so mild I figured ibwas just overtired, and I'm not supposed to start till next Wed anyway. Then I realized I am also spotting. I checked my birth control pills because I thought I hallucinated and was really on period week. Nope. I'm coming a week early.
I have not a clue what this is about, which is how I ended up searching the topic. I am glad we're not alone...so that tells me it's a "thing".
I'll be visiting a Dr of Naturopath next week and I'll be sure to find out WTF. LOL
