Wa'alaikum assalam! Honestly, cyst tak biasanya affect pregnancy test results, those tests detect hCG hormone, bukan affected by cyst. Tapi kalau OPK line samar dan test murah pun line samar, it could mean timing is still early or hCG levels belum tinggi lagi, so maybe tunggu a few more days and test again dengan first morning urine? A few of my mum friends also experienced samar lines during their cycle and ended up getting clearer positives a week later, so jangan worry dulu. Best jugak if you're concerned, boleh check with your doctor or call the clinic, they can do a proper blood test which is way more accurate than urine tests.
