Hi mum, I’m really sorry you’re going through this at 16 weeks, it sounds quite worrying especially with all the pregnancy hormones on top of it. Vasculitis during pregnancy can vary a lot depending on the cause and severity, so I don’t think there is a one-size-fits-all experience to compare with, but many mums do go on to have close monitoring and still deliver fine when it is properly managed by specialists. What I would really suggest is to stay very close follow-up with your gynae and the specialist managing the vasculitis, and don’t hesitate to go back earlier if symptoms worsen or new ones appear. Try not to read too many worst-case stories online because your case is very specific and your doctors will be the best to guide you through this safely.
