Hey me and my boyfriend have been having sex and I lost my vrginity to him on September 26 and we did it 4 more times after that and we used a condom and the pull out method every time. I was suppose to have my period on the October 8th and now it's the 10th and I'm really worried and I'm also not on birth control and I took a pregnancy test and it came up negative three days after I lost my vrginity I need HELP ASAP
