Sorry on phone so can't see any tickers etc. I took it while breastfeeding so if its ok for that it should be ok for pregnancy I would think, but definitely check with pharmacist or GP!
Taking while breastfeeding is not the same as taking while pregnant.

Get into the probiotics (take 2hrs away from antibiotics) and hopefully once off anti's things will settle down. Don't eat foods high in sugar as this feeds thrush. And if no improvement see your dr.
