Evening primrose oil

Ta
I was wondering if anyone has ever used or researched the benefits of taking this! I started last week taking this due to a friend saying it will help me cope with getting upset when AF comes. 
I was just researching online and the benefits are amazing. even with helping ttc. It helps produce more fertile egg white cm ( which I got my + OPK today and lots and lots of egg white cm) so I think it does actually work I'm quite impressed with it. Also U have to stop taking it once u have ovulated because it makes ur uterus contact and which could harm sperm/ not let them get to the right place they need to be. 
Just thought I'd let everyone know about it :) xx
