So I'm currently on CD 24, AF due on the 14th. Yesterday I went to pee and when I wiped there was dark red blood. A few hours later I went again and it was very light pink and changed to brown pretty immediately. Today I have very light brown discharge. I don't feel any different than normal, no moods or cramps. Could it be implantation? And when can I test? I'm supposed to have my wisdom teeth removed on the 14th, and be put under anesthesia.... so I'd really like to know.
