first time mommy

So I'm a first time mommy and yesterday I lost some of my mucus plug and today lost a little bit more of it. I called my doc office they said it was normal to lose your mucus plug in different times but then you lose your mucus and it has blood in it then it's time. Well i haven't lost it yet I'm 35 weeks and 1 day and I'm having light almost period cramps. When does labor usually come when u are losing your mucus plug? 
Please comment on some helpers I'm kinda freaking out🍼
