Hirap sabihin talaga, sometimes it's the mucus plug, pero sometimes it's just normal discharge na mas marami lang ngayong late pregnancy, kaya better to call your OB or go in para ma-check nang sure, para matulog ka ng mahimbing at hindi ka mag-alala buong gabi! One of my mum friends thought she lost hers two weeks bago pa magdeliver, so timing varies talaga sa bawat mama.
