So I've just gotten off a flight with my extended family after a week in Spain. We've all been bitten by bugs but yesterday my little sister had lots of 'bites' on her belly. We've just checked her again as she was itchy and they've spread onto her back - they're looking like chicken pox. I've been sat with her and holding hands etc. I'm 22+3 - should I contact my MW/GP? I had them multiple times as a child, not sure if this is relevant. Thanks!
