Anytime you start messing with your hormones, it can take a while to recover. They have been cases where the harsher forms (like depo) have permanently damaged a woman's fertility. I personally stay away from that stuff completely, and am very, very happy practicing Natural Family Planning, which has NO risk of physical side effects. If you'd like to see a short demonstration on how the Pill works, here's a detailed link. (http://www.familyplanning.net/main.php?parent_id=27&i...) Otherwise, you may consider this excerpt: (oh, and best of luck conceiving again! You sound like a very loving mom.)

"The recent press release of July 29, 2005 by the International Agency for Research on Cancer (IARC) a division of the world health organization (WHO), revealed the little publicized classification of combined estrogen-progestogen oral contraceptives (OCs) as carcinogenic. The IARC placed the contraceptive/abortifacients into its group 1 classification, which is the highest classification of carcinogenicity. This classification is only used “When there is sufficient evidence of carcinogenicity in humans”
Combined estrogen-progestogen OCs are the most commonly prescribed methods of artificial birth control. “Worldwide, more than 100 million women – about 10% of all women of reproductive age – currently use combined hormonal contraceptives”. Tragically, the WHO is only admitting “late” what was already reported in 2003 by the National Cancer Institute (NCI) and other scientific bodies that have found a substantially increased risk of several types of cancer among combined OC users, citing a “significant increase” of the risk of breast cancer, as well as an increase in the risk of cervical and liver cancers. What they failed to report is that millions of women are being given the same carcinogenic chemicals, particularly the poor in Third World countries, through the Depo- Provera injections, implants, patches, Intra-uterine devices, etc. Even though there is immediate danger to the millions of women, who are regularly ingesting or inserting “Carcinogenic chemicals”, the IARC did not recommend the immediate removal of combined estrogen-progestogen oral contraceptives from the market.
Your return to normal cycles will depend on how long you have been using artificial methods of birth control."
