Vitamin C is bad?

I was eating an orange today at work and a Co worker asked me if I'm trying to abort my baby. I just looked her with a WTF DID YOU JUST SAY!? Expression. She then informed me that vitamin C is a good wh to cause a miscarriage. I had no clue. Then she showed me a site she read it on. But I think it's sill nuts! Wouldn't my doctor tell me not to eat oranges. I had an ultrasound and they told me to drink lots of orange juice to get baby moving. Is it really bad? I love oranges 🤕
