Aih, itu normal lah! Especially at 5 weeks, sometimes the line boleh jadi very faint or even disappear and reappear depending on timing, urine concentration, and berapa lama dah test tu sitting. Hormon HCG tu memang naik berganda every 2-3 days during early pregnancy, so kalau kemarin klinik confirm positif, likely your levels are still rising, next few days UPT should show clearer lines. But honestly, since you already tested at the clinic kemarin and got confirmation, I'd say trust that result more than home test, clinic punya equipment lebih sensitive and they know what they're doing. If you're still worried about the faint line, worth checking back with your doctor or klinik just to confirm everything progressing well, especially to rule out anything like ectopic or slow-rising levels. Congrats, by the way!
Maybe error. Cuba repeat test. Kalau dah positive di klinik means you are pregnant
