Is Acidophilus pills safe in pregnancy ?

Hi, Is Acidohillus tablets (good bacteria) safe to take in pregnancy - I have been taking them for the last two weeks - am 12 weeks now - just a wee bit worried

[color=indigo:cgrgnfe1]What are they and what are they for?? I stopped taking all my supplements when I found out I was pg and just kept to the folic acid!! Ask your doctor / pharmasist!![/color:cgrgnfe1]
