Honestly, maraming pregnant moms ang nag-take ng evening primrose oil, lalo na towards the end of pregnancy kasi tingin nila it helps with labor, a few of us tried it din actually! But I'd really suggest checking with your OB first bago mo isimulan, kasi may considerations siya depending sa your pregnancy status at medications, and mas safe na marinig mo directly from your doctor kung okay ba talaga siya for you specifically.
