My LMP started on January 13th. I lasted 3 days. (which is normal for me). We had unprotected sex on Jan. 18, 25, & 31. On Feb. 8 I began spotting, brown in color and the next day I began having period like cramps, but still only spotting. Nothing on my underwear, just when I wiped. Last night, when I wiped, there was a tiny spec of very light red but mostly brown, and again this morning back to completely brown. My AF is due For Feb. 14. So I am just wondering does this sound like implantation bleeding, or early AF? Again, I am having NO FLOW at all, just light spotting when I wipe.. thanks! (: Sorry for TMI!
