Period late .

According to <a href="">EVE</a>, my period is 11 days late. I’m experiencing bad cramps, soreness in legs, mood swings (pretty much PMS) but no cycle . I’ve also been having a weird thick white discharge with a faint smell. I’ve been to the doctor, I don’t have anything and they treated me for bv. It could be a yeast infection, because I have a bit of discomfort. But I’m hoping it’s not pregnancy, I don’t think it is . Can anyone explain why my cycle is late ?
