Me and my boyfriend had sex but I had made him stop because it was unprotected and it was probably a little less then a minute long he had whipped off the precum before as well, two days before I had gotten off my period, and what are the chances of me being pregnant? I have a normal cycle 28-27 days? I wanted some help from some women that may know, oh and about a week and few days after I took a test it was negative? Should I be ok? We are both very worried
