I am 25 and normally have a 28 day period that is 4 days long--light to regular flow. On July 2nd, I took Plan B, within 72 hours, after my primary birth control failed. My period was due one week later on July 8th and I did get it. Two weeks later, I got a second period. This was longer than usual--about 7 days. On Aug. 8th, I got a third period that just ended didn't end until Aug. 16th. Now, on Aug. 17th, I am again feeling ovulation pains that I usually feel 2 weeks before my period.
I should also say that I have been unusually stressed lately. Could this combination really be causing the problem?
