Wa'alaikumsalam sis! Okay so two lines means positive lah, even if one line is samar, sebab any line yang ada tu means ada hormone tu, tak akan keluar kalau tak pregnant. A few of my mum friends also got the samar line first time, terus jelas sikit on the second test the next day. But honestly, since your lines are there and you're 3 days late, best you go see your doctor to confirm and get a blood test, HCG tu akan clearer and they can check if everything is okay especially since you had cramping. Congrats, mommy!
