It's probably related Mayaness. When your system is overloaded you can usually detect it in other ways - especially when PG and with a highly sensitive sense of smell. Can you stomach garlic? It is actually helpful for thrush - i know women who treat thrush and various kinds of BV (bacterial vaginosis) with garlic. You can eat it (a small, whole clove, raw and peeled like a big tablet twice a day, or 2-3 roasted cloves mashed up (easier to stomach/get in) twice a day, or garlic tablets (you need more though) or even as a pessary (thread cotton through a peeled clove (don't cut it, even to remove the bottom!) and push it into your vagina, remove after 20mins, repeat twice a day)). I know 3 women who managed to make sure their StrepB status was -ve for birth using garlic regimes.
