At 6 weeks 2 days

I feel so weak saying/feeling like this. But I cannot take this constant nausea, right along with excessive saliva ( ptyalism ). The way I feel, I feel like giving up.. This is my 3rd pregnancy and this one seems the worst so far. I hate to complain like this, it’s just a lot especially taking care of a 4 year old and 2 year old and still working a full time job. I just want to lay in bed and do nothing!!
