My doctor today told me that she would be doing the GBS test next week, ok my thing is I just bought evening primrose oil to start using tonight both orally and vaginally, for ladies who ve used epo before their gbs test, did u pass it? I am afraid that inserting the epo vaginally might cause bacterial growth, makin me to fail the gbs test next wk. Pls what do u ladies think? Can inserting epo cause bacterial growth?
