What Is The Best Method For Terminating The Pregnancy?

I am 10 weeks pregnant and a day and ive been very nervous about being pregnant because I made a terrible mistake and had un-protected sex on Aug 13th 14th 16th and 17th. The partner i had sex with did pull out and came in a towel. Then me and my husband had sex on the 18th of August and he didnt pull out he actually laid inside of me for a while. Then I found out I was pg the end of Aug. But me and my husband have a four yr old son and weve had unprotected sex multiple times and ive never gotten pg again by him. Although he has changed his diet since may 2011 and eats better exercises and dosen't smoke as much.
