I did it with primrose oil with my last pregnancy. Plan to start this soon. I would puncture a hole in the tablet and apply it with my finger. It really was phenomenal with preventing tearing. My doctor was impressed haha! 

I'm scared to try this, does it hurt??

My husbands doing it, with sweet almond oil. I couldn't reach 😆 

I had a really hard time getting the angle right doing it myself so my husband does, which is good as he can give a lot more pressure than I can. We use almond oil or coconut oil. There's several good websites to show how to do it

I heard to do it with coconut oil. I'm 33w5d tomorrow and haven't yet.
