Irregular period then chemical preg now a regular cycle?

Dawn
I went off the pill 10 months ago and have had irregular periods ranging anywhere from 5-10 weeks long. Last month (7 week cycle) I had a chemical pregnancy.  I am now cd15 and having left sided cramping and a small amount of EWCM when I wipe.  Is it possible that the chemical pregnancy regulated my cycle? Or that I am indeed ovulating right now?
