Anybody breastfeeding while pregnant?

Morgan

I’m still nursing my almost 19 month old and she doesn’t seem to be letting up nursing anytime soon and I was planning on tandem nursing. I just had my first prenatal appointment talking to the nurse and she said I need to start weaning her. I’ve read that you don’t need to according to the American Pregnancy Association and I don’t want to wean her if I don’t have to. It would literally be impossible to.. Anybody in a similar position?
