So I was supposed to start as of yesterday. 10-28-15 by all 3 of my calenders that I follow. I have been spot on for at least the last 6 months. I took a test and it was negative, but I don't remember how many days late I was on my other 2 pregnancy before I had a positive test. I'm getting anxious with the not knowing. And I also am not having any types of pains or cramps indicating that I'll start. Helps please
