How to Get Pregnant on Birth Control

How to Get Pregnant

There are times when you might ask how to get pregnant on birth control for very good reasons. Perhaps you are trying to avoid getting pregnant and are concerned because most methods are not 100% effective at all times. Then again, you may be looking to have a baby even though you are taking the pill to regulate menstrual cycles for medical reasons and not as a method of birth control. For whatever reason, understanding how to get pregnant on birth control is possible by considering a few facts and figures.

Step 1: Understanding that No Method is 100% Foolproof

One of the biggest concerns that many women have is in relation to birth control efficacy. If you are trying to get pregnant on birth control, your chances are slim. The most effective methods of birth control, and thereby the least effective in terms of getting pregnant are hormonal methods. For instance, if you are using Norplant that has a 99.9% proven record of efficacy, your chance of getting pregnant is slim to nil. As a matter of fact, most of the hormonal methods are at least 99% effective in preventing getting pregnant. However, prophylactic methods are considerably less effective and present the best chance of failure. A birth control sponge is only 91% effective while a male condom is 97% effective.

Step 2: Medications

Now that you understand that no method is 100% foolproof, you can take it a step further by taking note of medications that interfere with hormonal birth control methods. Drugs like Rifampin which is an anti-tuberculosis medication as well as Griesofulvin, an antifungal, are both known to decrease the efficacy of hormonal birth control pills. Also, many doctors are aware of the fact that antibiotics such as Tetracycline and Ampicillin counteract the potency of birth control drugs. Antiepileptic medications as well as certain barbiturates, speed up the degradation of oral birth control pills by stimulating liver enzymes to quicken the metabolism of those drugs. If you are looking for ways to get pregnant on birth control pills, these medications may not be a viable option, but the potential is there nonetheless.

Step 3: Defective Prophylactics

Another means of getting pregnant on birth control is defective prophylactics. Because of the fact that prophylactic birth control methods are by no means as effective as hormonal methods, defects present an even greater risk. Whether or not you are actually looking for ways to get pregnant while using prophylactic methods of birth control, this would be the easiest way to get pregnant while being 'protected.'

Step 4: Missing Doses of Birth Control Pills

Unlike implants and patches, birth control pills make it easy to miss a dose or two. Whether missing doses intentionally or unintentionally, the more doses you miss the greater the odds will be of becoming pregnant. Second to missing doses is taking them at irregular intervals. Because these medications have a standard half-life, missing a dose by even as short a time as a few hours can significantly increase the risk of the medication failing. The failure of the birth control pill is directly proportionate to your chances of getting pregnant. If you are trying to get pregnant on birth control it is often a simple matter of missing a dose or two.

Step 5: Nausea and Diarrhea when Taking Oral Contraception

Another factor that reduces the efficiency of oral birth control is nausea within the hour after taking the pill or extreme bouts of diarrhea. The shorter time that medication has to be absorbed into the system, the less effective it will naturally be. The little that is left in the system after being purged will not have the potency as a full dose would have. When trying to understand how it is possible to get pregnant on birth control, look for times when you were nauseous or had diarrhea during the month of conception.



As there are really no 100% guaranteed methods of birth control, it is always possible to get pregnant, no matter how slim the chance. Even tubal ligations have been known to reconnect allowing for an egg to drop and eventually get fertilized. Whether you are trying to understand how to get pregnant on birth control because you want to, or want to avoid getting pregnant, it is good to be aware of how it can come about and what you can do to control it. If you are trying not to get pregnant, it is advised that you use more than one method at the same time.
