Hi mama! At 6 weeks pregnant, some white discharge is normal, but yung thick clumpy kind ay better checked with your OB just to make sure it's not a yeast infection or something na kailangan i-address early, a few of us moms had that din and ang doc agad na-clear it up with safe treatment para sa pregnancy. Since wala naman siyang lumalabas sa undies, it's probably okay, pero don't wait, mag-appointment na lang kayo para peace of mind mo at ng baby mo! Congrats sa pregnancy, by the way!
