I'm 6 weeks and my symptoms seem to completely change each day, and within the day. Yesterday I was on the verge of vomiting all morning and couldn't eat anything, but then suddenly got to lunchtime and my appetite kicked in and I couldn't stop eating! Then felt very nauseous during the night but this morning feel OK and so hungry. My tiredness really comes and goes to, sometimes feel really energized and sometimes so tired. First time so finding it very confusing!
