Anyone take Diclegis in first trimester?

This is my third pregnancy and by far the worst for nausea and vomiting. I’m nauseous 24/7 and vomit several times a day. I’m at the point where I can’t function anymore. My doctor prescribed diclegis to help but I’ve been so nervous to take it. I’m only 7 weeks pregnant and I get so nervous about taking anything besides vitamins during pregnancy, especially in first trimester.

Just wondering if anyone has taken it with previous pregnancies or is currently taking it? Does it help?
