HELP ME !

daryl briiana
Hey y'all , my name is briiana and I am nineteen . & I am currently four weeks and two days late . I've taken at least four pregnancy tests since my last period and they were all BPN . I figured i would have at least have a VFL , but I haven't . my fiancée and I have been trying to conceive for eight months now . this isn't my first pregnancy , but I am having all the symptoms of being pregnant : morning sickness , urinating every two minutes , and my hair is falling out , extremely vivid dreams , and killer heart burn . I haven't taken a test in a week because I'm scared of a BFN , again . what is wrong with my body ?! what should I do .
