Hay, 37 weeks na yan so you're almost there na! Honestly, every pregnancy is different, a few of my mum friends had minimal discharge towards the end while iba naman sobrang dami, so normal lang yan. But since you're asking and might be worried, mas better magpa-check ka na lang sa OB mo, especially pag may changes or nag-feel ka ng something off, para may peace of mind ka na talaga.
