Aih sayang, I know this is confusing! But honestly, samar lines can be tricky, you really need to see a doctor or do a proper blood test (beta HCG) to be sure, especially after trying for 5 years. A few of us mum friends have gone through the same thing where the lines were unclear, and the blood test gave us the real answer, so don't rely on the kit alone. Take a deep breath, whether positive or negative, a doctor will confirm it properly for you. Sending you all the best, okay?
