So 8 days before my expected period (18th) I started to spit a brownish color when I wipe nothing, and barley anything on my pad (a few spots) for 2 days. My period is "expected" the 26th. This has never happen to me. I always am have regular periods... Anyways the spotting lasted the 18-20th. Now all I have is lite cramping, not bad for me to complain, and I've been crazy tired lately and hungry. Any suggestion? Can I be pregnant?
