Baking Soda

Jessica • I`m 33 & my hubby is 28. We are working on baby #1 for 3 years now!
I had someone tell me about a couple who had major infertility problems & went to the Dr's. Anyways, that didn't help so a lady they went to  in NOLA told them about a baking soda douche that helps with the PH of the vagina. They tried and were positive within 6 weeks. Has anyone else heard anything about this? Or tried it?
