Sayang, any leaking during pregnancy tu kena check dengan doctor ASAP yah, even if it's just a little, better safe than sorry! Could be many things (hormones, pressure, even amniotic fluid), but only a doctor can tell for sure dengan proper check-up. A few of my mum friends experienced similar at different weeks, and turned out okay, but each pregnancy is different so jangan delay okay? Call your clinic or go to hospital lah, they won't think you're being paranoid, preggy mums, we gotta listen to our bodies! Let me know how it goes, sending you hugs!
