My boyfriend lost his virginity to me two weeks ago. He couldn't stay hard with a condom on so we didn't use one. He usually doesn't have any pre-cum(I have given him enough blowjobs to know). He didn't come anywhere in or near me(we had sex a lot afterwards and the same situation occurred). My period is suppose to start tomorrow and I've been having my normal symptoms but I'm worried that I may be pregnant. What should I do? I cannot go buy and pregnancy test
