Wa'alaikumsalam! Lendir putih telur macam tu memang boleh keluar during pregnancy, especially bila hormon meningkat, tapi sebab you're only 10 weeks, I think best you check with your doctor or gynae just to be sure everything's okay lah, a few of my mum friends experienced something similar but better safe than sorry, kan? Doktor boleh tengok directly dan give you proper peace of mind. Semoga everything's well with your pregnancy!
