So my period came at the expected time this month, but it behaved differently. Normally I spot bright red and it gets moderate to heavy and stays that way for about three days. Then it tapers off into dark brown. This month i spotted a light pink with bright red in the middle and it became my normal amount of blood but only stayed for two days then tapered off. I know I'm probably being paranoid, but is there any way this could be implantation bleeding? It didn't seem fit any descriptions I've seen and I've been pretty stressed recently, but I'm still nervous.
