I have never had sex before and am not on any type of birth control. My boyfriend fingered me but had not ejaculated yet. I am concerned about any pre ejaculation that could potentially have gotten on his hand and then into me. I am scared and do not want to take plan b because I do not want to put anything in my body that does not need to be there, and I know there are side effects. However, should I be concerned I could be pregnant? This happened on the 16th day after I got my period, so I am also scared I was ovulating. Also, it is coming up on 72 hours since this happened and I do not know what to do. Please any information you can provide would be greatly appreciated.
