The first thing you need to know is that there are two types of emergency hormonal contraception.
One is ulipristal acetate, the main ingredient of the most effective morning after pill ellaOne*. The other levonorgestrel, a common hormone found in birth control pills.
“Levonorgestrel is ok to take while breastfeeding,” says Sim, “although small amounts of the hormones in the pill may pass into your breast milk, it’s not thought to be harmful to your baby.” says Sim.
So what about breastfeeding after taking ellaOne? “The safety of ellaOne during breastfeeding isn’t yet known. The manufacturer recommends that you don’t breastfeed for one week after taking this pill. During this time, it is recommended that women express and discard the breast milk in order to stimulate lactation,” Sim explains.
If you choose to use ellaOne, we recommend you discard breast milk for seven days after taking the pill.
