Saya cek upt mnggu lps 6/12 2line tp samar2..lpstu mnggu ni 12/12 saya period.. sesiapa prnh alami?

Samar yg terlalu samar or samar yg jelas nampak double line? Boleh check lg harini, supposedly yg samar tu dah makin pekat if betul pregnant. And kalau pekat, bleeding tak normal so kena terus jumpa O&G. But if upt harini negative, probably chemical pregnancy
