There are lots of great alternatives to the pads and tampons you see advertised on TV.
There are cloth pads. These are washable pads made out of materials such as cotton and flannel. Girls and women who use them report these pads are softer, drier and just feel more comfortable than disposable pads. Plus, cloth pads don't contain the chemicals disposables do.
Cloth pads are available online and possibly in traditional retail stores. They are also available at certain health food and natural health stores. There are also women who make them as a cottage industry.
One alternative to tampons is the menstrual cup. This is a bell-shaped device made out of silicon. It is inserted in the vagina. It also does not contain the harsh chemicals of disposable pads and tampons.
Menstrual cups are available online and at some brick and mortar stores.
There are also disposable menstrual cups made out of a safe plastic material. These are available online, at certain retail chains in the U.S., at Shoppers Drug Mart across Canada, and at other retail outlets in certain parts of Canada.
I have some posts on this blog with links to places that sell these types of things. Type either cloth pads or alternative menstrual products into the search box on this blog to find them.
If you find yourself craving sweet stuff around the time of your period, reach for honey or maple syrup instead of chocolate because those things are better for you. If you are craving salt, eat sea salt because this contains a lot of beneficial minerals.
There are lots of natural remedies to deal with PMS.
If you stain, do the traditional thing of tying a sweater or jacket around your waste while you walk to the bathroom. Depending on the nature of the stain, however, you could opt not to cover up at all. After all, it happens to a lot of girls and your period isn't something to be embarrassed about.
If you are in a place where you can't change or get a pad, there are ways to improvise these things.
If you're really stuck, look up freebleeding online. I would tell you to be careful about what results you click on, but if you're reading this blog it's obviously useless to tell you not to look up inappropriate things on the internet. (ha ha)
