What should a woman with thrombophilia or a history of thrombosis take note of when on birth control pills?

My opening advice is to encourage you to use a reliable family planning method at all times, if you are sexually active and are not planning to start a family. Of all reversible methods of contraception, the hormonal methods are the most effective; and the birth control pill is one such method. The birth control pills are far more reliable than the normal use of condom. As with all medications, birth control pills have their fair share of side effects. The majority of the listed side effects are infrequent.

First and foremost, the primary contraception action of the oral contraceptive pill is that they prevent ovulation of an egg from the ovary. The oral contraceptive pills also change the nature of the cervical mucus especially during the fertile period by making it more hostile to sperm survival and motility. Finally, the oral contraceptive pills thin the endometrial lining making it harder for an embryo to implant. The oral contraceptive pills are very effective (as long as you are taking them correctly as instructed) and are associated with a low failure rate.
