I'd like to hear your views/experiences?

Lauren
I'm currently 33 weeks pregnant, I've been drinking raspberry leaf tea since 31 weeks and introduced the capsules last week at 32 weeks. 
I'm going to start taking evening primrose oil orally at 34 weeks and then vaginally at 38 weeks.
Anyone able to give me any insight or share any experiences with me?
I'm aware that these products do not 'induce labour' only prepare your body for the big day so am willing to give them a try. This is my first baby so it's all new to me.
