i agree with clysta.. if there was no penetration chances of pregnancy are very slim.. it must be one of the above reasons.. and remember body cycles tend to change any time they might not be perfect.. i guess u should wait for some time and still late consult a doc.. good luck..

If there was no penetration it's not technically deemed to be 'sex' it's just a sexual activity, but to the best of my knowledge starting any of those can indeed mess with your cycle. Depending on your age your cycle might still be irregular, as well as a dozen other things. (stress, medicines, rapid weight gain/loss, change in diet, exercise, etc) From what you've described though, pregnancy would be extremely remote.
