I found this:
Common breastfeeding concerns - Drugs and breastfeedingContraception
If you want to take the contraceptive pill while breastfeeding, you should
only be prescribed the mini-pill. Common brand names include Microlut,
Noriday, Locilan and Micronor.
Combined oral contraceptive pills – like Nordette, Microgynon, Triphasil,
Triquilar and many others – should not be taken.
The morning-after pill (Postinor-2) is quite safe for emergency
contraception.Depo-Provera and Depo-Ralovera (both three-monthly injectable
contraceptives) are excreted into breastmilk in very low amounts, and are
also safe for use. They should be given about six weeks after the birth.
If you are planning to use implanted contraceptive devices (such as
Implanon or Mirena) small amounts are excreted into the breastmilk
and you should discuss the risks and benefits with your doctor prior to
implantation.
