Researchers are looking for better ways to help women prevent pregnancy. Every month, a woman's body prepares for pregnancy in a process called the menstrual cycle. When pregnancy does not happen, menstruation occurs. During menstruation, women lose blood and tissue from inside the womb. This bleeding can last for about 2 to 7 days. Hormonal intrauterine contraception aims to help women prevent pregnancy by stopping the process of the menstrual cycle. Intrauterine means that the contraception is in the form of a device that is inserted into a woman's womb by her doctor. The device then releases the contraception into the womb. Researchers have found that when women use hormonal contraception, the disruption to the menstrual cycle can cause changes to how often and for how long women will bleed. So, the researchers in this study want to learn more about the menstrual bleeding patterns of women in Spain who are using hormonal intrauterine contraception for the first time. In other words, In particular for the LNG-IUSs, irregular bleeding due to the local effect of levonorgestrel on the endometrium is common, particularly during the first 3 months of use, and it is of interest to know if this is a major reason why Spanish women discontinue this very effective method and what other factors may be associated with discontinuation. The researchers will then use this information to estimate how many women choose to stop using the contraception. The participants will be able to enroll in this study after requesting hormonal intrauterine contraception from their doctor. They will be women between the ages of 18 and 35 who have never used hormonal intrauterine contraception before. The participants will visit the study site 3 times. On the first visit, they will receive the hormonal intrauterine contraception. The doctors will also check their health to make sure they can join the study. The participants will visit the study site again 4-12 weeks later, and one last time after 1 year of having the hormonal intrauterine contraception. During these visits, the doctors will ask the participants questions about any medical problems they have and if they want to continue using the contraception. Throughout the study, the participants will use a mobile app to track information about their menstrual bleeding and how they feel about it.
