what should I do????

me and my boyfriend had sex 5 days before my period and the day before my period. we used a condom but it broke before he came, he said he dont think he got any in me. I took a pregnancy test and it came back negative. my period is supposed to be coming on today.. should I take another test or go to the doctor for a blood test? or is it too early? im not feeling any early pregnancy symptoms besides sleeping alot...
