It was not an intercourse but in fear i took Ipill .I took it on the day after that thing happened.It was around 18 hours later of that thing happened.I was sure that nothing happened but in the morning i had vomit,so in fear i took it.I was empty stomach.Then after half an hour i went for latrine. After that i did'nt feel anything like any cramp,back pain,headache,mood swings etc..just nothing.My periods was normal and on the correct time and correct day and in the next month also i had periods on normal time and its flow was normal.I just want to know that what happened to the pill?Did it work inside me?If it worked then why no side effects? Please Answer.Thank You.
