Hay, I understand kung bakit ka nag-aalala! But please get a blood test (beta hCG) from your doctor or clinic, that's the most reliable way to know for sure, especially with faint lines at this point. Home tests can be tricky kapag very early pa, and your period tracker might be off din, so better mag-consult na lang para walang doubt. A few of us mums have been there, and getting blood work done really took away the stress, you'll have a clear answer in hours. Keep me posted if you need to talk!
