What I was really trying to say, before I got all flustered by a problem editing my first post, was that the hormonal state present during breastfeeding may allow effective contraception with a milder form of birth control pill than would otherwise be used. Sometimes called "mini pills," the birth control pills intended for use during breastfeeding have moderate does of progesterone only. Such pills usually do not interfere with lactation, unlike pills also containing estrogen. Examples of progesterone-only contaceptives approved (by FDA in the USA) for use during breastfeeding include the Micronor pill (made by Ortho-McNeil, see http://www.orthomcneil.com/healthinfo/wome.../different.html ). However, every situation is different, so these may or may not be right for any given person. Hence, my suggestion to discuss this possibility with your doctor.
