I need major help or answers. Me and my boyfriend decided to go without protection for my bday. Had sex on June 15th and he pulled it hit he said a dot or so went in a little as he was pulling out. My cycle is due to come on July 6th. Since a few days ago I’ve been getting really hot and my stomach has been sounding weird and I’ve been tired. People tell me it’s to early for those symptoms and that I’m crazy and to not worry. I’ve taken 4 test and they all came back negative. I don’t know what to do. Now I actually hope I am carrying but it seems as if I’m not. HELP?
