Sugar Bear Hair Vitamins

Since I found out I was around 5 weeks pregnant on Thursday October 22nd. I have continued to take my hair vitamins on top of a multi-vitamin. I just got prenatal vitamins and will start taking those in place of my multi-vitamin. But it just occurred to me this might not be very safe considering how much biotin is in them. I know too much can cause a miscarriage. Until I get to my doctor this next week, and I can some peace of mind. Have any of you mama's taken these before and have already talked to your doctor to know if there safe or not while your pregnant??? It does say on the bottle to consult with your doctor before taking if your breastfeeding or pregnant, that's partly why I'm freaking out a little bit. I hope I didn't take too much already.
