evening primrose oil for TTC?

I bought the 500 mg ones and I’m wondering it anybody has seen improvement in cervical mucus from using epo? I’m going to start next cycle since i’m on cd10 and it’s too late but i’ll just wing ttc this month and start tracking with opks. I’ve been ttc for 11 months now and next month will be a year. I think we weren’t successful because we didnt dtd a lot, but now we agreed to dtd more often, so 3-5x a week from end of period to the next. I’m hoping that it’ll really happen.
