It's for sure not the morning after pill. Dosage timing and visit schedule sounds similar to a mifepristone script (RU486). If it is, shes basically getting a miniabortion (when its just an embryo). It's going to make her feel like shit (physically speaking) so you should probably be there without asking too many questions/passing judgment.
