i think so, i get it :/
Before you start your periods, you get a "discharge" of which is the yellow crust. Its completely natural. It starts off as being a light colour but closer to the start of your periods, it turns to a caramel color. Don't worry, every woman gets it ;)
Yes they can. Some even before that age.
You can't stop your periods once they start, they are a natural and healthy process that your body has to go through. Once a period starts there are medications that can stop, but these will only be used in special circumstances by your doctor, such as if you've been bleeding too long.
Sounds like timing or fueling issues.
That is the discharge being thicker because you are ovulating so yes.
One 5mg tablet a day is the dosage for postponing your periods with Regestrone. Start the medicine four days before your period should start. Do not take for more than 14 days.
