Sigh can't manage a next sad face

I took a HCG test monday and got a BFN and was heart broken bcuz I have been working on baby #2 for the past 6 months now. Got up yesterday morning went to the ladies room and saw a streak of blood like my period about to start heart broken again so I got upset took a shower went to work but I realized that I don't see no spots nor nothing even when I got home after 11 pm last night still nothing. My period is due the 28 which is almost two weeks from now, I know I have to do the two week wait before I do a next test but I'm going out my head excited to take a next test but fair of only seeing one line or not pregnant. Can I get some advice please.
