How long does it take (how many periods) does it noramlly take before getting into a regulare cycle. I've only had 2 so far and I hate it soo much, but luckly It hasn't happened during school. I want to know about when will it be normal because I don't want to be at school without a pad and it happens. I can't deal with that kind of embarrament.Please help me and give any advise on the begining of regular periods.The first and second were around 4 months apart.Just to be clear I really don't like it I just wish it wasn't random.
