Questions on (possible) pregnancy

I'm 18 yrs old and am three days late on my period. My cycle has been consistent for a couple of years now, so this is out of the ordinary. I'd had sex several times in the two weeks before expecting my period, sometimes unprotected. I realize that unprotected sex increases the chances of a pregnancy, but I suppose I stupidly justified not using protection by recalling the numerous different times that I'd had unprotected sex and not gotten pregnant in the past two years. But I now have a creeping suspicion that I may possibly be pregnant due to a few bouts of recent fatigue, lack of energy and strength, late period, etc. So, it's most likely possible that the time of conception was about a week ago if I am at all pregnant. Three days into what is supposed to be the beginning of my period, would a pregnancy test accurately be able to tell? Or should I wait about a week or so to take the test?

Secondly, if I do happen to be pregnant (and forgive me for my unrelenting and strange stance), I already know I would want to terminate the pregnancy, despite the fact that an abortion is shunned amongst my family and even my boyfriend. However, as it is my body, I will decide what I want to do with it; I would only need help and support in the process. Because such a surgery is unacceptable and disapproved of, my family will most likely refuse to help me. My boyfriend, though he would be more easily convinced than my parents, isn't as resourceful. With a lack of money, transportation, just resources in general, I have no idea where to start. I welcome any pieces of advice, comments, help that anyone can offer - anything would be greatly appreciated.
