Birth Control Pills & Potential Pregnancy After Dry Humping: What to Do?

Question
Hello,

My doctor told me to start talking Birth Control pills starting the fifth day of my period,which happened to be the last day of it (on saturday 7/1). Everyday I am taking the pill, and for the first week I took them all on time. On the third day (9/1) i had a sexual act with no intercourse (dry humping with clothes on) and my bf didn't cum on me. Later on some foreplay followed; I'm am almost 100% sure my bf had no sperm on his hand, but IN CASE he had, do you think there is a big pregnancy chance?? How effective is this pill?? i have heard that i was supposed to start talking it from the 1st day of my period, but i went with what my doctor had told me!!

Thanks for your help!

Answer
As long as you started by the fifth day of a normal period, you're protected by the pill immediately.  There is no pregnancy chance.  The pill is extremely effective (1 pregnancy out of 100 couples taking the pill for 1 year) as long as no pills are missed.
