Pregnancy and chicken pox

Kerry

Ladies could anyone help.. I had my niece and nephew last Monday till Wednesday but my nephew went home Tuesday with a bad chest and breathing problems I had midwife Thursday and everything was fine but my nephews mum has just text to say he’s came out in chicken pox, do I need to ring my doctor tomorrow? I’ve had chicken pox when I was little but being a first time mum I’m not sure what to do I’m 25 weeks pregnant
