I've got it!Quigley - Here's the solution that worked for me. I too had a yeast infection from 5 weeks to delivery with my son. It was AWFUL to say the least. I tried the vaginal yogurt, using a peri bottle with tea tree oil/water, garlic, limited diet, etc. Nothing worked. Finally, just before I got close to my due date, my midwife told me to try this: pharmacy grade boric acid. Here's what you do - you can get the boric acid at one of those Mom & Pop pharmacies (the big ones like CVS and Eckerd won't have it). Get four size "OO" capsules from them as well. Make your own each night. Put one in your vagina each night for 2 nights in a row. Skip a night and then do it again for 2 more nights. It was amazing! At least I was able to deliver without a raging yeast infection! As soon as he was out, the infection was gone! I think for some of us, it is just the way our bodies handle pregnancy. I've got another one now. (Aren't we the lucky one?) Good luck and let me know if you have any questions.
P.S. This is stronger than the yogurt and garlic remedies, but more gentle than Monistat, etc. I guess the medics used to use it all the time before the drug companies came up with a more expense and marketable product.
