Stopping BC after 10 years.

Just wondering how long it took some other ladies to regulate after stopping BC after being on it for an extended time? I've been on BC for about 10 years (originally started to regulate and lighten my periods). I stopped taking my BC on February 21st (the end of the pack), had my period the 25th-28th and have had nothing happen since. I've had the regular mood swings/emotionalness and a bit of acne, but AF has been MIA. We aren't trying to prevent pregnancy at this point and since I'm off cycle I've tested twice and they were negative.
