no, it's nothing to worry about.
really??? what is it?? Do you know why it happens?
For the most part, yes, it's totally normal. Though if you notice a lump or something else, then I'd have it checked out. Eventually it will go away on it's own and it's just part of development with the fluctuation of hormones. It can be caused by certain medicines as well. Also try not to keep checking for the discharge because that may make it more persistent.
