I've been feeling extreme constant nausea since Sunday afternoon. I vomited once on Sunday evening but not since. The nausea hasn't subsided, I've got a slight temperature and a cold. I've done a pregnancy test which was negative so definitely not morning sickness. Don't think it warrants a visit to the GP as I can still get on with my day but just getting really fed up with feeling like I need to be sick for the last 72 hours. Any ideas - I'm not on any medication, haven't eaten anything suspicious, no other health issues and Dr Google isn't helping as I'm not actually being sick (other than the once on Sunday evening)
