Raspberry tea and Mucus plug

So I read that drinking red raspberry tea should help make labor easier.... I'll be 36 weeks tomorrow this is my 5th and I've had all mine at 37-38 weeks.... Well I drank a cup yesterday and drank a cup this morning and I am losing my mucus plug today in pieces(but no blood) and having some cramping.... My doctor said to just monitor it... Anyone else have a similar experience? I've lost my mucus plug with one of my previous pregnancies but there was blood...
