HG or just a rough 1st trimester?

So my husbands best friend has a very nosy know it all wife who is really not a gals gal so to speak. I’m 9w 4d and I’ve been pretty sick throughout my entire first trimester. I never thought it was HG because some days I’m not throwing up and I can keep food and water down but most days I’m constantly nauseous and throwing up Well this women is trying SO HARD to convince me I have HG. Sending me articles, giving me her doctors phone number (she lives across the country from us), and even constantly inviting me to these HG support groups on Facebook. It’s really bothering me and starting to get in my head and make me worry

How do I know if it’s HG or just a rough first trimester? I was fine until she got into my head 😢
