Morning,noon & night sickness 🤢

Am currently 7 weeks & 3 days & for the last week have felt nauseous from the moment I wake up to when I go to bed.I’m not actually vomiting,but would probably feel better if I did!I can only describe it as the worst hangover ever 😩 I remember feeling nauseous with my son,but was working full time then & don’t remember it being this bad.I only work part time now & am struggling to not let work find out yet,but if it carries on like this I may have no choice.The only time I don’t feel sick is when I’m in the bath or asleep.Have tried mint (tea & sweets),ginger (tea & biscuits),sour sweets.I have the midwife Friday,but is there anything I can actually take to help ease this at all??😷Thank you in advance!
