The Progesterone Only Pill works by making the cervical mucous thick so sperm can not get through. This pill does not prevent ovulation, like the combination pill (typical estrogen/progesterone pill).
It is 99% effective when used together with exclusive breastfeeding.
It is only 94% effective in non-breast feeding women.
The progesterone only pill can be started at any point in the cycle and provides effective contraception after 7 days. It must be taken at the same time daily. There is no placebo week.
If you miss a pill or are 3 or more hours late in taking, resume the progesterone only pill and use back-up contraception (i.e. condom) for 48 hours
Once you are supplying 50% or more of your baby’s nutrition w formula or food, it is best to switch to a combination (estrogen/progesterone) pill, which works by suppressing ovulation.
Please let us know when you are no longer fully nursing & if you have a pill preference based on prior pill usage. Please confirm your pharmacy is current when you call to change to a traditional pill.
Because the POP works by making cervical mucous thick and because Estrogen thins cervical mucous, the POP may be less effective when used with vaginal estrogen for breastfeeding-related vaginal dryness & atrophy. If you are using vaginal estrogen, you may want to consider different options.
Other lubricant options are: Coconut oil: oil based, do not use with condoms
