You also have multiphasic pills that were introduced 10 years after progestin was made available to the public. Just like the others, the person has to take them at a specific time. Some say this is an improvement than those which came out in the past because of reduced number of incidents of side effects associated with birth control pills such as amenorrhea, breakthrough bleeding and spotting.
Biphasic pills can change the level of hormones once during the menstrual cycle. Some examples of these include Jenest, Mircette, Necon 10/11, Nelova 10/11 and Ortho-Novum 10/11.
The third type is called triphasic since it contains three different doses of hormones. Taking them will gradually increase the dose of estrogen and progesterone into your body. Examples of these includes Cyclessa, Ortho-Novum 7/7/7, Ortho Tri-Cyclen, Triphasil, Tri-Levlen, Trivora, and Tri-Norinyl.
There are emergency contraceptive pills or ECP but these are not supposed to be used as a contraceptive. It is designed to protect the woman after unprotected sex and so far, only one pill has been approved by the FDA and this is called plan B that contains the progestin called levonorgestrel. The difference between the other birth controls pills to this is one is that you can purchase this over the counter.
What type of birth control pill should you use will depend on what your doctor will recommend after you have undergone your medical evaluation. One thing that you may have to deal with regardless of what you take is the side effects. Until such time that doctors have developed a better pill, this is something you will have to deal with to prevent getting pregnant.
