I'm 6 days late, I took a test the first day of my missed period at night and it was negative. I haven't taken Another yet. I have a little bit of a back ache and peeing more often than normal. Also having twinges near my ovary every now and then. No cramping whatsoever. Other than being pregnant, what would make my period late. My cycles are longer, normally 35-37 days, I'm on day 45 now.
