Help no more throwing up?

So I am 7 weeks 4 days. The past couple days I have taken unisom and b6 to help with morning sickness. I still wake up and gag but I don’t feel the constant nausea all day. Just gassy, and tired. Should I be worried that I’m not as nauseous or is it the medicine just working? I’m trying not to worry I just hear people talking about their symptoms dissapearing usually meaning a miscarriage.
