Emergen-C and Airborne!!!

Really quick backstory: I work for a Chinese company in America and with the whole coronavirus news on TV all the time, for the last two weeks or so, I would take an airborne or emergen-c once a day, sometimes I would skip a day.

I didn't even think to read the label, but everyone online says that overdosing on vitamins can lead to miscarriage, and I'm freaking out.

I'm 11 weeks today, does anyone have any advice? I haven't noticed a change in symptoms or intense cramping, or anything like that, and I have an appointment on Thursday, but I figured I would ask here!

Any help is appreciated!
