Please whatever you do don't have an abortion unless that is what you want to do. YOU being the important word. Don't listen to your husband or anyone else. And nothing wrong can come out of it. my friend had her daughter while she was on the pill the whole time(as well as the morning after pill). She is happy and healthy and talking your ear off all the time at 11months.
I too conceived on the morning after pill and the baby is perfect. I am currently 29 weeks and have had three ultrasounds. The Morning after pill is only a higher dose of hormones, so there shouldn't be any effects on the fetus if only taken once. Please reconsider abortion. I am a maternity RN just so you know my background.
