hello, First of all, you need to confirm intrauterine pregnancy by doing one blood test for beta HCG and one TVS scan for viewing gestational sac. I-pill contains levonorgestrel which is progesterone and does not causes any ill health effect to fetus before 4 weeks or confirmation of pregnancy. So, she has nothing to worry about this. Start to take folic acid supplements, protein rich diet, avoid long journey/heavy work, maintain personal hygiene, take adequate bed rest and repeat scan after 4wks of first one for detailed feto-placental well being including cardiac activity/ fetal pole etc. Do periodic check up and complete suggestive investigations. Be well & take care.
