Can i be pregnant. my boyfriend pulled out. took 2 test and both negative. had symptoms of pregnancy.

Maybe....: It depends on when those pregnancy tests were taken. Were they negative at least 2 weeks after the incident? If not then you can't really be sure you're not pregnant until you get your next period. My best advice for you is to use a condom every time for intercourse. The "pull out" method is a terrible form of contraception. High failure rate if you're not trying to conceive.
