Is Ulipristal Safe in Breastfeeding

I am a breastfeeding mother and i want to know if it is safe to use Ulipristal? Is Ulipristal safe for nursing mother and child? Does Ulipristal extracts into breast milk? Does Ulipristal has any long term or short term side effects on infants? Can Ulipristal influence milk supply or can Ulipristal decrease milk supply in lactating mothers?

Ulipristal is a selective progesterone receptor modulator used in a single dose as an emergency postcoital contraceptive. No information is available on the clinical use of ulipristal during breastfeeding. The manufacturer recommends avoiding use of ulipristal acetate during breastfeeding; others recommend withholding breastfeeding for 24 hours after use, based on the low levels in breastmilk.[1][2]
