Nausea 9dpo

Hoping to hear from others who have experienced morning sickness and share how it feels. We've been TTC for 2 years and gotten pregnant 3 times all ending in early MC. I did not have nausea for those times.

at 8dpo I woke up from feeling like I'm going to throw up (felt like I had an empty stomach and starving feeling)

Today at 9dpo I woke up with waves of feeling like there's an empty pit in my stomach which almost hurts but not necessarily feeling like vomiting. Doesn't feel good.

I'm also feeling low back pain and twinge here and there. I really feel like I'm pregnant this time, but it's too early to test as they've already come back negative.

I was also out with friends at 7 dpo and had a headache out of nowhere and even had to take advil but at that point it didn't really click In.
