if after your january period.. you didn't have any unprotected sex anymore. You are safe .. no worries, just relax and have proper diet and sleep. :)

If you haven't got your period in 2 months and that isnt normal for you i would defiantly go to the doctor just to make sure everything is alright and not pregnant. If you are very stressed about it that also could make you not get a period. Just go to the doctor and see what he has to say just to make sure :)
