sick and tired of neg. test .

I am so tired of taking test and not even getting the faintest of a positive, for the last two days I've tested and they came back negative all I could do was cry , my period is in three days , I am 11 or 12dpo and I feel like time is dwindling down . it's just so sad that everytime I go to test I get this big burst of faith but the BOOM a big fat ass clear as day negative!!!! I am so sick and tired of this shit. and like right now I'm cramping right at the top of my pubic hair lining. Has anyone gotten at least a faint positive past 12dpo ??? I really need an encouraging talk or something cause this has gotten me down and out . I'm tired of giving myself false hope. 😭😭😭😭😭😭😭
