Annoying Bleeding On Birth Contro Pills: The DL on BTB

Women expect effective cycle control as well as effective contraception on their birth control pills. A common question every gyno gets is what should I do and: why did I have unusual bleeding on my pills. Sometimes it’s a fee spots after intercourse, and that is unlikely to be a problem with the pill. Sometimes it’s just an early or late period, which we call “unscheduled bleeding.” Most often it is what your physician calls Breakthrough Bleeding or BTB. If it’s not enough to need to use a pad we just call this bleeding during your pill pack spotting. BTB and spotting are common during the first few months of taking oral contraceptives. If you have BTB you are not at risk for pregnancy, and women should not stop their pills if they get BTB or spotting. BTB usually is caused by shedding of the lining tissue as your uterus adjusts to a new thin state in which it is fragile and thin. Breakthrough bleeding is more of a problem with the current, extremely safe, and lower dose birth control pills. BTB on birth control pills is annoying but almost always resolves without any treatment within two to three months. If you are on a pill that takes few or no breaks in hormone use during the year, BTB is more common.  Forgetting a pill can also cause breakthrough bleeding, and is more common than other reasons of BTB.. It’s less common for consistent pill users who have been on their birth control longer and often will only happen if you miss pills or take a medication that interacts with your pill. So if you miss a pill take it the next day with that days pills. If you take two pills together like that you should be covered against pregnancy. But if you miss more than two pills most physicians will tell you to use back up. Although the World Health Organization (WHO) states that no back-up or emergency contraception is needed unless three or more 30 to 35 mcg ethinyl estradiol pills have been forgotten (or two or more 20 to 25 mcg pills). And if you use back-up contraception be sure to take it for full seven days after two missed active hormonal pills, regardless of dose. If the missed pills are in your first week of the cycle and unprotected intercourse occurs during this week, use of emergency contraception (morning after pills) could decrease the risk of pregnancy. Some women on very low hormone birth control pills will sometimes have their own ovarian estrogen still produced, this is called follicular development. It probably still doesn’t increase risk of pregnancy, but should be discussed with  your health care provider. Other causes of BTB can be due to smoking cigarettes or taking a medicine that interferes with your pill hormone level. In those individual circumstances you probably should talk to your physician right away. If you have a bit of BTB, keep track of it, notify your provider, but most likely you will be told to just monitor it for a bit. After 2 cycles of unusual bleeding you should be seen by your doctor to have both your cervix and uterus checked. You may be given tests for pregnancy, for infection and/or an ultrasound. But most likely it's not something serious that needs to be treated, just something you need a bit of patience for.
