I would suggest contacting the following sources. They are very likely to have more positive information for you about which birth control methods are safe while breastfeeding.
For example, this source seems to question what your doctor said about your needing to have him weaned before you can start on the pill that you want. It looks to me that their only concern is the milk supply, not any harm to the baby.
"Hormonal methods
Controversy surrounds the use of hormonal birth control methods in breastfeeding women, particularly regarding when they should be started and whether or not combination oral contraceptives should be used. Resarch has not shown that the estrogens and progestins used in oral contraceptives (OCs) ingested by the mother are harmful to human infants, but it is known that estrogens can reduce milk supply in some women. Croxatto et al. and Peralta et al. have shown that combination oral contraceptives have a “moderate” inhibitory influence on lactation even if instituted after milk supply is well established.(4,5) Tankeyoon noted a 41.9 percent decline in milk volume with combination OCs.(6) The American College of Obstetricians and Gynecologists states that the use of combination pills is acceptable if women are informed of the risk of a decreased milk supply.(7) It is prudent to avoid their use in women who are committed to continued breastfeeding since many other choices are available.
The progestin-only oral contraceptives, injectable progestins, and progestin implants (presently unavailable in the US) have been studied and found to have no adverse effects on breastfed infants.(8,9) When to start progestin-only methods is also a cause for considerable discussion. Initiation of lactation is stimulated by the withdrawal of progesterone that occurs after delivery. Kennedy et al. suggest that one should wait at least three days before administering a progestin.(10) However, there are many anecdotal reports of milk supply being affected by the administration of a progestin-only contraceptive. Although Koetsawang noted an increase in milk supply with progestin-only contraception, Tankeyoon noted a 12 percent decline in supply with oral progestin-only contraception compared to placebo.(6,11) Waiting until at least six weeks postpartum to prescribe progestin-only contraceptives may avoid such effects."

Another source says,
"A small amount of the synthetic hormones in these contraceptives does enter the milk, but there is no evidence that this is a danger to the baby. Follow-up studies have revealed no long-term problems in babies and children who continue to breastfeed while their mothers use hormonal contraceptives, with or without estrogen. Some physicians, however, do question the use of hormonal contraception in lactating mothers because of possible unknown effects on their children's long-term sexual or reproductive development." And then it goes on to describe what your options are....
