Hey mama! Yan ay pretty common sa pregnancy dahil tumaas ang hormones, but since you're 15 weeks in and this is your first time, mas safe na i-mention mo ito sa OB mo sa next check-up para ma-rule out lang any infections, better safe than sorry talaga, especially ngayon pa lang kayo sa pregnancy journey. A few of us mums noticed ganyan din, pero important na ma-confirm ng doctor kung normal discharge lang or kung kailangan ng treatment, kaya go ahead and ask! Wishing you a smooth pregnancy po!
