Nausea Advice?

Hi! I’m 7 weeks pregnant today with my second baby. I had a little bit of morning sickness with my son, but it was never as bad as this one. I find it hard to eat, because I feel sick after eating anything at all. I also get nauseous as soon as I open my eyes. It just doesn’t subside, it’s all day everyday. And when I try to get sick (TMI), to let it all out, I just end up dry heaving or having stomach acid come up.

I messaged my OB but until she responds this week, does anyone have any good advice? Or anything that helped them?

Thank you in advance❤️
