Im 20. previously for a few months i took laxatives. i took quite alot but have stopped for maybe a few weeks? but no period for four months pls help

See your doctor.: there are many potential reasons that you have missed your period for four months. First, you should be checked for pregnancy. If you are not pregnant, then you need a check up to help determine why you're not having periods. It is not likely that it is related to your laxative intake. I would not resume the laxatives, but I would see your doctor to get checked out. Good luck.
