Fertility Forum - Pregnancy Scare (please Help)

Hi, I've been very scared and stressed out over this and I could use a little feedback. I also apologize in advance if this is not the proper forum to post this. I am sorry if this is gross to some but I need to get the details out.

First off, im a male and last week me and a friend of mine were fooling around with eachother. She gave me oral and I ejaculated. I wiped the ejaculate off my penis (i didnt not ejaculate " a lot" and it didnt leave a "mess") and then afterwards me and my friend proceeded to fool around more, we were mostly dry humping completely naked. We did not have intercourse and there was NO PENETRATION whatsoever and I never felt my penis touch her vagina and at times if I thought it was getting close I would put my hand over my penis to cover it so there would be no contact. After we were done I noticed that there was a little amount of sperm on my stomach (due to the position of my penis when she was laying on top of me ) so i started freaking out that some of the sperm may have gotten near or onto my friend's vagina and possibly impregnated her although I never felt my penis make contact or graze her gentials... but you never know. If any sperm did get on or near my friends vagina it most likely would have been just a little bit, but I know it only takes one sperm to fertilize....

I told my friend about this and she got a little worried and went to the doctor about 5 days later. The doctor gave my friend both a urine and blood pregnancy test and both came back negative. The doctor told her there is nothing to worry about and every thing is fine.

The thing that still makes me worried is that as I did some reasearch online regarding pregnancy tests i read you should wait about 10-14 days after your "encounter" to get tested because sperm can live up to 5 days in a females vagina before fertilizing an egg? So now im worried about whether or not a pregnancy test after 5 days is too soon and there is a chance that she can still become impregnated?

Then again, the doctor knows a heck of a lot more than me and wouldnt have given my friend the tests and told her she is fine if he felt it was too early to test correct? Do doctors give different kind of tests????

Im just so worried and thinking of every little thing that can go wrong. I just really want to put this all behind me.

So what are the chances that me and my friend are in the clear and she will not become impregnated?

Also, I know, what we did was stupid and careless. Believe me I am paying the piper for it.

Thanks for listening.
