Hi, I did sex with my bf on 16th at 5 PM then on 17th I look a pill called unwanted 72 at 6 PM but after one hour I vomited and then I vomited 2 more time on the same day. On 18th I again took an unwanted 72 at 7: 30 PM and after 2 hours I vomited again so what I need to do now. And in my case only semen was there in the dick also my periods ended on 31st December. Kindly help me as soon as possible is there any chance of pregnancy.
