Faint line tests

Hope Faith • I`m 29 and happily married.. 4 MCs. Rainbow baby born Nov 2016. Rainbow Baby #2 due Oct 2018. Mommy of girls! PCOS warrior.
I had two faint line tests and one digital that read yes. I got my blood test and my levels are low.  But no one else I see on here is experiencing this? Should I be really worried? Has anyone experienced to this and everything turned out at the end? I want this baby more than anything in this world. Next week I go in for another blood test to see if my levels have doubled. Fingers crossed. Please wish me luck.
