Reassurance!

Ok ladies I've been taking this off brand probiotic for 3 months now, I'm currently 27 weeks. I just now have brought it up to my provider as I thought it would be no big deal. But she just told me that it makes her nervous that I've been using an off brand! Whenever you hear the word "nervous" come out of your doctors mouth it makes you ten times more nervous right?! I'm just scared that by taking this that I have hurt my baby girl or have been giving her something that is not good for her! I'm now the nervous stressed out one as I could have prevented taking this in the first place 😔 I know you ladies aren't doctors or anything but do you think this could have affect on my baby girl?
