HELP! Rephresh Pro-B?


So I’ve been getting yeast infections constantly throughout this pregnancy (sorry tmi for some). And I thought I might try taking a probiotic to help. I’ve read good things about this Rephresh Pro-B, but of course there’s nothing indicating whether or not it’s safe. Has anyone taken it while pregnant, or spoken to their OB about taking probiotics while pregnant? From what I’ve been able to find there doesn’t seem to be any indication that the body absorbs any of the bacteria cultures, it just helps maintain a regular ph level? Help!!
