So I have gotten my period a week early before but only twice in my life. I'm a little worried because I started bleeding but very light late friday early saturday morning. Its a pinkish red color not my normal heavy dark red flow for AF. I'm also cramping but not bad enough to take medicine yet. If it doesnt stop by Monday I will call the doctor just wanted any input! Af ended the 17-18 and we BD'd the 21 23 25. Bleeding started late Friday night the 26th. If this is my AF its 12 days early and extremely light!
