And this lady told me that it's not FDA approved and unless I want to get pregnant, don't take it. But the lady who sold it to me says she takes birth control and it doesn't interfere with hers. But there are different types of birth control so idk. All I know is I was so excited to grow my hair out and now I may have just wasted $40. Can anyone help me out here? Is this safe to take while I'm on this?
