Any success with taking Evening Primrose Oil?

Miss Hawai’i

Well I’m at 7 moths ttc, no diagnosis of infertility, and just about desperate! 😑 Let’s see... I’ve tried preseed, prenatal vitamins, drinking less to 3 beers for the whole week, caffeine decrease to a cup of coffee two times a week, Chinese herbal fertility supplements by bioterra, hips on the wall after sex, and now trying primrose oil from Cycle day 1 to 14.
