I'm sorry if this picture grosses anyone out but I'm kind of stumped. Ovulated 1/19 & AF due 2/4. Woke up this morning to this. AF is usually heavier than this and almost always on time. Wondering if this could be implantation bleeding or just an abnormally light AF. I just get this when I wipe, it's not enough for me to need a pad or tampon. Not super crampy either, just teeny ones that are barely noticeable.
