Hello, I am an 18 year old girl. I had sex without a condom and my boyfriend came inside. 20 minutes later I took the morning after pill. However, it is worth mentioning that I had been ovulating for 7 days and the semen was still inside when I took it and for 20 more minutes. I'm afraid it won't be effective and I'm thinking about taking another one. Could you tell me if it is safe please? I'm desperate
