When prescribed a progestin-only pill, you will likely be instructed to take it within the first five days of the start of your cycle, which is typically on the first day of your period. Unless you have a shorter cycle, 23 days or less, the pill will become effective immediately if you begin taking it within the correct time frame. If you do have a shortened cycle, it can take two full days for the pill to become effective at preventing pregnancy.
If you start the combination pill on the first day of your period, you should be protected right away. If you start the combination pill at any other time during or after your period, it can take a week to become fully effective, so use a backup form of contraceptive during this time to avoid getting pregnant. There are two types of birth control pills : the progestin-only or mini-pill and the combination pill.
Each works in similar ways using different types and amounts of hormones. You must take either type every day to prevent pregnancy. Combination pills contain both the hormones estrogen and progestin, which work together to prevent ovulation from occurring. They also cause the cervical mucus to thicken and the uterine lining to thin to further prevent sperm from reaching an egg.
Some types of combination pills have 24 active and four inactive pills. Women typically get their period during the week of inactive pills. For the best protection, take your combination pill at the same time every day.
As long as you take them within the same hour period each day, however, you should be protected against getting pregnant. Generally, you need to abstain from sex or use back-up contraceptives such as external and internal condoms or diaphragms for about a week to prevent pregnancy. To prevent pregnancy, you should use condoms for at least seven days after starting hormonal birth control pills i. If you started using the transdermal patch Xulane , birth control implant Nexplanon , or hormonal IUD Kyleena, Liletta, Mirena, and Skyla within the first five days of your period, there's no need for back-up contraceptives.
Outside of that time frame, you'd have to use the barrier method for the seven days after starting your birth control. You need to use a form of barrier contraception for at least seven days after receiving the hormonal injection Depo-Provera. If you had the shot within the first week of your period, a back-up birth control won't be necessary.
However, if you are concerned about your abnormal vaginal bleeding, you can consult your health care provider for medical advice. If you miss taking the pill for two days or more, you are no longer protected against pregnancy.
When you restart a birth control packet, you need to use a backup contraceptive for seven days. In order for the hormonal injection to be effective, experts typically recommend that you get a shot every 10 to 12 weeks. If you wait longer than 15 weeks to get your next shot, then you're at higher risk of pregnancy and should use a backup method, like condoms, for seven days following your next injection.
The steps to take if you miss your birth control patch differs depending on your patch week and the number of days you missed before applying a new one. Some doctors recommend starting it on a Sunday so that any spotting you may experience will not disrupt your weekend. While it is okay to start birth control before your period, it will take longer for you to be protected from pregnancy. For this reason, many doctors recommend taking it towards the end of your period or immediately after it ends.
Some pill packs contain placebo pills, which do not contain any hormones. When these pills are taken, you will bleed. This is not a period, but rather withdrawal bleeding that occurs due to lack of hormone. It is also possible to skip your periods altogether by only taking pills that contain the hormone. You may experience spotting during the first few months on the pill, as it takes some time for your body to adjust to the new hormones.
However, over time, you should notice lighter, more consistent periods. It is possible to get pregnant, even if you take birth control. A common cause is taking the pill inconsistently i. Furthermore, if you take the pill l ess than you are supposed to — this depends on your specific pack — you are at a greater risk of becoming pregnant.
