Eh, clear mucus boleh jadi a few things, sometimes it's just normal discharge yang increase during pregnancy, tapi 3 times dah kluar macam tu better safe to check with your doctor just in case, especially since your first one didn't have any warning signs like this. A few of us mums in my group ada experience different things with each pregnancy, so takde yang exactly sama. Your doc can do a proper check and tell you if it's the mucus plug or just normal discharge, so jangan worry lah, just get it confirmed okay!
