In one sentence, describe what the following article is about:

Some progesterone creams are available over the counter, while others require a prescription from your doctor. You should ask your pharmacist about different options, and ask for details about the differences. When applying anything to your skin, make sure to read the ingredients and make sure that you do not have any known allergies. If you decide to go with an over the counter option, you might want to try your local natural health store. Homeopathic remedies can be very successful, and you can ask the staff at a small store any questions you may have. You might receive more personalized advice than at a large chain store. While generally considered safe, progesterone can cause some unwanted side effects. Some users have reported issues such as upset stomachs and weight gain. Others have noticed depression-like or PMS-like symptoms. Remember, this cream contains hormones, so it will affect you physically. Before you start using progesterone cream, discuss your options with your doctor. Explain your concerns, and what you hope to gain from using the cream. Ask all of the questions that you have, and gain a clear understanding of what the cream can do for you.

Summary:
Research different creams. Shop around. Know the possible effects. Talk to your doctor.
