At this point without doing a test of any kind is a 50/50. However 3 months is a long time. Your best bet here is to see your doctor, confirm if you are or are not pregnant, via blood testing as this is much more accurate. If you are not pregnant, it would be best to do further evaluation so that you can become more regular with your cycles.
