Usually tanning does not cause a change in your cycle but sometimes your body can be stressed and go through hormonal changes even if you do not feel stressed. Diet can also cause a change in your cycle and you are low weight so this also could be causing this to occur. If you are having no pain or other signs of or bleeding I would first recommend you take a pregnancy test if you are sexually active to see what the results show and if they do show negative you should consult with your physician about putting you on birth control pills which help greatly for regulating your cycle when your hormones get off track. And even starting a new job can cause minor stress that you may not feel but your body does, so I would monitor it for one more month and if there is still some irregularity you should talk with your physician about a prescription to help regulate your cycles.
