maintance help

So recently i reached my weight goal!! :) so now each week i increase my calories by 100. So from 1300 to about 1400 and so on. i did my weekly weigh in and i gained two pounds. i just want to clarify what to do next if this happens, do i keep increasing or lower down? I know this might be normal but i wanted to make sure that i wont gain more than 5 lbs if i keep doing this. and will i still get my goal weight? Any suggestions how to approach maintaining my weight?
