Hello dear I understand your concern You had sexula intercourse and now want to prevent the pregnancy. I will give advise step by step: 1. Unwanted 72 pill/emergency contraceptive pill: If 72 hour has not been crossed then you can take unwanted 72 to prevent the pregnancy. 2. If 72 hours has been crossed then wait for the period to come. If period will delay by the 8-10 days then go for urine pregnancy test and or blood HCG to confirm the pregnancy. If you will be pregnant then you can terminate the intrauterine pregnancy by abortion pill containing MIFEPRISTONE AND MISOPROSTOL. It is safe during the breastfeeding, and very successful in termination of pregnancy. But for better result it should be used under the supervision of gynecologist. No abortion pill/unwanted 72 will protect against the pregnancy for next 2 year. You can use contraceptive like birth control pill, condoms, contraceptive patch to prevent the pregnancy in future. You can meet the gynecologist and choose best contraceptive method after sex counselling. Meanwhile avoid stress, take healthy diet, do regular exercise like walking and yoga, drink plenty of water Hope this may help you Contact HCM for further health query Best regards Dr. Sagar
