Please help. Could I be pregnant?!

I had resolved to stay a virgin till marriage!. However, today my bf and I got a bit carried away and wanted to get a taste of what sex might be like!. He used a condom!. I cannot think of doing it without one!. Since it was my very first time, I was nervous and not properly lubricated I guess!. He kept making attempts to penetrate me, but failed each time!. Every time either he totally missed, or it wouldn't go through fully as I was too 'tight' and thrashing about nervously!. Only a couple of inches managed to go inside me (I think just as far as the 'head' of his dick), and I just thrashed about and made him pull out!. After trying a couple of times, we gave up our attempts without making any progress!. But my concern is, could there be any chances of pregnancy whatsoever!?!? I am really scared and unsure!. So much is at stake, and I just cannot get pregnant yet!! He did wear a condom, and even while he penetrated by an inch or so a couple of times (for a couple of seconds each), I thrashed about and eventually didn't let him do it!. I would like some informed answers please!.

Additional info: it is 5 days since I had my last periods!. Not sure if this is a so-called 'safe' time or what!. Www@Answer-Health@Com
