Each month, the uterus prepares for a possible pregnancy. The lining of the uterus thickens into a cushion of blood vessels, glands and liquid. When a female becomes pregnant, this lining will nourish the fertilised egg for the term of the pregnancy. If the egg is not fertilised, then the lining (mostly blood and some fluid) passes out through the vagina. This bleeding is called a period, or menstruation.
Why is it important to have good privacy settings on social media?
Using social networking and social media sites are easy ways to chat on-line, make new friends and keep in touch. However, there are some risks with meeting people online if you don’t already know them or haven’t met them in person.
When talking and sharing thoughts and information online with people you don’t know or trust, keep in mind that once a message, photo or video is shared, there is no control over where it goes. Good privacy settings help ensure that you have control over who you ‘friend’.
Not sharing the password, setting your profile to private and not accepting friend requests from random people are good standard practices.
