Nausea

I’m so fed up and it’s getting me down. I’ve had nausea from 5 weeks pregnant. I vomit sometimes though it’s become more frequent in last month. I’m nearly 13 weeks now. Docs gave me some anti sickness meds to try recently and I vomited them up and gave me blurred vision. Trying another medication now but so far it’s not working. I’m just getting over covid too. I’ve just had enough now and it’s making me so sad n fed up. I did vomit throughout my first pregnancy but this nausea is constant i actually prefer to vomit. I’ve had time off work lately and I’m just exhausted. I can’t take much more of it.
