First day of lmp was 6/14/14. Usually my cycles are pretty regular (28-32 days). My husband and I sometimes use the natural family planning method to avoid pregnancy rather than use a condom. I usually pay very close attention to when I ovulate and it's quite obvious when I do because I get a lot of egg white CM and soft cervix between days 14-16. This cycle, rather than getting egg white CM on days 14-16 I had watery CM and figured I was probably ovulating, but that my CM was a little off because I had a lot of stressors and diet change. I had unprotected sex and my husband ejaculated inside me on 7/7/14 (3 weeks after first day of lmp). What was pretty dumb on my behalf is that in retrospect all the stressors going on in my life (traveling, moving, diet change, minor surgery and illness), usually prolong my menstrual cycle. So the day after intercourse I had really, really fertile looking egg white CM that I could stretch more than 10 centimeters. 18 hrs after intercourse I took plan b. This morning, a week later, I had extremely light, brown-tinged spotting (just enough to wipe on a piece of toilet paper). Would I still apt to spot a week after plan B or would this more likely be implantation bleeding? I have no symptoms other than slight breast tenderness which is common for me with any hormonal change.
