Feeling nauseous and weak during the first trimester

Hi girls! I've read a lot of articles about pregnancy but I wanted to know if you all are feeling the same way as I am. I'm 7w 1d pregnant and I've been feeling so nauseous and weak this past week that I'm getting a little worried. I had some gastrointestinal discomfort but I was able to work around the house and be active. Since my Doctor prescribed me Progesterone last week everything changed . Please let me know if any of you are going through the sam? Kisses to all of you :)
