So I've been slowly losing pieces but just now there was a huge peice that I lost. Is it normal to have a small hint of blood in it? Just like a little pink. And also how soon do people normally go into labor after losing it? I'm 38w 4d and I've been having contractions. Last doctor appointment I was 1cm and 80% effaced.
