Anything to take the feeling sick away?

Libs • 💍June 2016 👶🏼🌸 May 2017 👶🏼pregnant baby no 2

So today is my lil ones 1st birthday and we are throwing her a party. I’m currently 5 weeks. However I am feeling extremely sick and have tried ginger biscuits I don’t want to ruin the day but I feel dreadful. I don’t recall feeling sick when I had her. Any suggestions to take the edge of the sickness a lol is greatly appreciated.
