Wa'alaikumassalam sis! Congratulations on the two lines, I can feel the hope and worry in your message, 4 tahun tu memang banyak sabar. Honestly, those budget tests dari eco shop boleh jadi accurate especially kalau dah nampak clear two lines (hormones tak tipu, even at RM2.10!), but because you're only one day late and takde symptoms lagi, the best move is to go see your doctor or do a blood test, at least then you'll tau 100% sure and tak perlu overthink. A few of my mum friends actually got budget test results confirmed at the clinic and memang betul, so the test itself isn't the issue, but your peace of mind after 4 years of waiting adalah more important than any uncertainty. Do get it checked properly, yeah? Wishing you all the strength whatever the result.
