GBS + and Evening Primrose Oil

I’ve tested positive for group b strep, and I’ve already started taking 2000mg of evening primrose oil capsules orally. I’ve only been on it for a short period of time but from my research it seemed like a great idea considering I am 39 weeks and 4 days. I have an appointment with my OB GYN tomorrow and of course plan on telling him (as I forgot last appointment). I’m just worried that if my labour is super quick like research shows, that I won’t have my 2 doses of antibiotics while I’m in labour.

Does anyone else have experience with GBS and primrose oil? Or even just one of the two? Advice would be greatly appreciated! Xo
