I’m 7 weeks tomorrow and just feel like I am falling to bits. Normally I am fit and healthy but this week my wisdom tooth has been playing up, which is giving me a sore neck and tongue. Back ache, nauseous and I have just noticed my belly button is red raw and bleeding slightly. Is the belly button thing anything to be worried about? Gave it a clean and applied antiseptic cream but it just seems to be one thing after another!
