What's this?

Ay sis, at 32 weeks that's likely just extra cervical mucus from the pregnancy hormones and irritation from the internal exam kahapon, totally normal and common, hindi pa yan ang mucus plug talaga! The mucus plug is usually thicker, more jelly-like, and may kaunting blood or brownish tint, kaya different ito sa what you're describing. Since you just had the transvaginal ultrasound and IE, your cervix is probably just extra irritated which is triggering more discharge. That said, keep an eye on it lang, if it becomes bloody, increases a lot, or you feel cramping, better to message your OB right away para ma-check lang, pero honestly based on your cervical length (2.6cm is decent pa), you're probably fine! A few of my mum friends went through similar scares during their third trimester at lahat turned out okay naman.
