Brief Answer: Belongs to category X drugs Detailed Answer: Hi, Thanks for the query. Usually unwanted 72 will give protection against pregnancy when taken within 72 hours of the unprotected intercourse. But the efficacy of the tablet varies from 50 87%. So, sometimes pregnancy is possible even after taking the pill. Unwanted 72 contains levonorgestrel. It belongs to category X drugs in pregnancy according to FDA. Means it is considered to be contraindicated in pregnancy. But according to few studies there is no increased possibility of neonatal anomalies after taking the pill. Reference : WWW.WWWW.WW So, if the pregnancy is precious to you and you want to continue the pregnancy, better to continue with regular antenatal checkups and ultrasound examinations. Anomaly scan at 11 weeks and TIFFA scan at 18 weeks are mandatory to detect any possible anomalies. If no abnormality is detected you can continue the pregnancy with your doctor's advice. Hope I have answered your query. I will be available to answer followup queries. If you are satisfied with the answer, please give your review at the end of the discussion. Take care.
