Aww first time mom ka, totally understandable ang alalahanin mo! Pero kailangan mo talaga i-check with your OB agad kung ano exactly yung lumalabas kasi maraming posibilidad, baka normal discharge lang (which increases during pregnancy), baka may infection, or baka something else na kailangan i-monitor, hindi kami dapat mag-assume dito kasi importante talaga sa 28 weeks. One of my mum friends din nag-alala sa ganyan at turned out okay lang after check-up, pero better safe than sorry, bes! Let me know ano sabi ng doctor mo, sending you hugs!
