Pregnant! Please help!?

Hello! I've been doing some serious thinking... can I be prego? I'm only 16 and can not deal with a child. So far I haven't had any symtoms of pregnancy, such as breast hurting, back pain, craving for food, feeling like I gained weight, ect.. Although my stomaches been hurting (not bad but a tiny bit.) My friends say it's in my head & my boyfriend tells me I'm not either. My boyfriend wore a trojen condom & pulled out when he did his thing (with condom on). When he took his condom off he blew into it to check for air holes. I don't think there were any, & even if there were a tiny one, can i still become pregnant? I'm SO scared! My parrents would make me break up with my boyfriend if I was pregnant, but not only that I don't want a kid! Not now!!! Help :( Am I worrying too much? I don't want to buy a pregnancy test in fear of stressing out over "false" results. Last time I had sex was on the 29th of June, it's now the 2nd of July... help!!! PLEASE!
