Cyclizine in pregnancy

Ra

What’s your thoughts/experienced on taking this anti-emetic whilst 9 weeks pregnant?

I’ve been prescribed this today. I’m miserable with nausea and vomiting. Some days I’m vomiting 4 times and have nausea 24/7. I don’t really want to take medication but I can’t go on like this. I’m worried about harming the baby. The doctor says it’s safe. I’ve lost 3lbs since falling pregnant which isn’t a lot. Am I being selfish if I take this?
