The choice of birth control is a very personal decision every woman has to make. While you can choose to use some contraception methods on your own (such as condoms or abstinence), others require a consultation with your ob-gyn who will determine if the birth control you find the most convenient is suitable for you.

Your doctor will pick the most suitable contraception for you depending on some factors.

1. How often you have sex
2. How old you are  
3. When and if you plan to get pregnant, as many contraceptives have different durations and fertility restoration periods.  
4. Health condition. You may be denied use of oral contraception if you have deep venous thrombosis, breast cancer, liver disease, etc.   
5. Hormonal levels do matter when it comes to hormonal contraceptives, as each of them has different doses of synthetic hormones
6. Lifestyle. Smoking is the main contraindication for oral contraceptives. If you’re inattentive and likely to forget to take the pills every day, you shouldn’t take them
7. Breastfeeding  
8. Your medical history, namely possible diseases and/or surgeries you have or have had  
9. Allergies that have been previously observed  
10. Any present gynecological pathology (endometriosis, cancers, etc.)
11. Peculiarities of your period

Women with quite heavy periods have reported to have light menstruations with no or little cramping after inserting an IUD with low levels of progesterone and zero estrogen
