Hi,
During first time, you used withdrawal method and took
postinor 2 within 24 hours. It is highly effective in preventing
pregnancy around 95%. But in second time after using condom, you did unprotected sex. Withdrawal method is not successful in preventing pregnancy.
Precum may enter in to vagina unknowingly and it contain sufficient sperm concentration that cause pregnancy. If sex done during fertile phase the there will be chance of pregnancy. So if you did sex during fertile phase of cycle, better to take postinor 2 second time to prevent pregnancy. Period may be delayed by 1-2 week, earlier and excessive bleeding can occur. If your next period will delay by more than 2 week then go for urine pregnancy test and or blood
HCG test to confirm pregnancy.
Avoid
stress, take healthy diet, drink plenty of water, do regular exercise. Use condom always to prevent unwanted pregnancy.
Hope I have answered your query. Let me know if I can assist you further.
Regards,
Dr. Dholariya Sagar Jayantilal
