So I started cramping yesterday, sometimes it was almost period like but more dull. It continued this morning but when I got up this morning I went pee and checked cm-- didn't feel a whole lot. Went and laid back down. 30 minutes later I felt wet so I went and wiped and it was quite a bit of cm with a brown tint. I am 10-11 dpo and AF is due on the 19th. Does it sound like implantation bleeding??
