Wa'alaikumassalam sis! Aww I understand the anxiety, kabur lines are so stressful kan. Honestly, kalau double line naik (even if faint) especially petang, that's usually a sign of pregnancy hormone, not PCOS je lah, PCOS wouldn't cause the line to appear macam tu. Since your doctor dah advise upt 2x weekly, I'd follow that closely because line baru keluar biasanya means HCG rising, so either it'll get darker or tak, and that will tell you everything. Best bet is go back to your doctor with these test results so dia can do a blood test (HCG) or rescan, that's the only sure way to know either way and get proper clarity
