Complicating relationship and possible pregnancy....

Ok, i have been seeing this guy, he was actually the first crush i ever had when i was little, but he lives 5 hours away from me.... he came down 2 weekends in a row and of course, we ended up having unprotected sex, no pull out, and im not on birth control..... Well, after the 2nd weekend, he went back home and after a couple days, i started hearing from him less and less.... his job does make him work hard and for long hours so i understand the concept og him being exhausted from work and whatnot.... but now, i have a big issue because idk when i will get to see him again, and i might be pregnant.... i took 3 pregnancy tests, 2 came out positive and the other 1 negative.... he is supposed to send me money Friday to go to the dr to get a better pregnancy test and possible sono to see what the deal is.... i need advice.... idk what to do...... this guy has always been a huge oart of my life and i love him dearly but the distance and possible pregnancy has got me stressing....
