Too much vitamin B?

My doctor had me start taking a Super B Complex vitamin a few months before I conceived. I didn’t think to ask whether I should discontinue this at my confirmation appointment and now I am worried. I am about 5.5 weeks along.

I’ve mostly read and heard that any excess vitamin B is excreted through urine... but I went down the Google rabbit hole and it seems that too much of particular vitamins can be risky... but stopping them abruptly also has the potential to be risky.

I’m not sure what to do. Anyone have knowledge of this topic?
