Evening Primrose Oil- please respond

This goes out to those of you who have experience with taking this oil. I have some concerns about it I would like to extinguish. 
1. Is it safe to take both vaginal and oral? And what meathod are you taking it ? 
2. Is this your first pregnancy taking it or did you for others as well? How did that go? Better labor? How long after you started taking it did you give birth? 
3. Any side effects? 
4. How do you recommend taking it (dosage included) 
5. I was considering opening a capsule putting it in my red raspberry leaf tea instead of taking the capsule oral, good idea or nah? 
6. How do you get the capsule into your vagina close enough to your cervix? 
7. Anything else I should know? 
THANKS FOR THE HELP c:
