Stomach bile, vomiting for over a week???

Last period: 1/4-1/8

Next period: 5 days away (2/7)

Ovulated: 1/19-1/25

I don’t really have any other symptoms of pregnancy besides this vomiting & i’m extremely tired. It usually happens at night, started almost 2 weeks ago. It was up until yesterday a quick process. I’d feel nauseous, start to feel hot, get clammy & shortly after I’d vomit once & feel instant relief. As the days go on, it’s becoming a come & go through out the day sickness. I’m vomiting 3-4 times a night. Instantly when I wakeup in the morning I have the overwhelming feeling that I’m going to be sick.

I’m concerned because if this is pregnancy, I definitely want to be doing everything I can to make sure I’m intaking as much nutrients as possible between throwing up...

I’ve done some researching, but not much I found that were pre-missed period.

Any advice or personal input is appreciated.
