So a little more than a month ago (August) I had to use plan b because a condom broke the day after my period ended. About a week later I started a light period for that lasted about a week. The day before my normal period was due for September, I had a doctors appointment where there was a urine analysis and pregnancy test was negative. Now, a week and a half after my typical period would have ended, Im still waiting for another menstrual cycle. I took another pregnancy test, negative. I suspect that my next period will come around the same time the light period occured after I took plan b, which is in a week. Does this all sound normal?
