Raspberry leaf tea capsules and Primrose oil capsules

34 weeks and started taking these to try and dilate, and soften the cervix since this is my first. Has anyone had any good outcomes from these? Also, am I aloud to take them both at the same time and how many can of each can I take in a day? I only ask because with the tea you're generally aloud to have as much as your heart desires. I've also been eating a pineapple a day, I know these don't always work for everyone but just thought I'd try. Has anyone had any positive/negative outcomes from any of these methods? Please share!
