I have always thought that birth control is not healthy at all so I have never been on any type of birth control. My friend was admitted to the hospital yesterday bc she has a large blood clot in her brain, they are doing everything to get rid of it but at the same time know what caused it. They had just informed us that her birth control could have caused it. She was on the shot for 5 years and had the pill for a couple months and the started the Nuva ring about a year ago. DONT TAKE BIRTH CONTROL, JUST BE RESPONSIBLE!
