Pregnancy Risk After Emergency Contraception & Birth Control Change

Question
Hello,
I usually take bcps but this time i started a new pack and took only for a week and stopped 4 days later my period came. On the 4th day of my period I had some dry humping and my bf came on my ass which we directly wiped off.
Few hours later I took Norllevo, an emergency contraceptives and later on started again my bcps.

What are my pregnancy chances?

Answer
Sandra,
I found this question in the question pool at allexperts.com
This means that whoever you asked the question to could not answer for some reason. So I received your question. So has anything happened since this date? I don't recommend taking emergency contraceptives. This could cause side effects and alter your natural period. Has your period come? Let me know so I can further advise you. Please email me at CHERYL51@aol.com and put ALLEXPERTS in the subject line of your email.

Sincerely,
Diane Cheryl
