I need some serious help!

Im 12+4, I have had no morning sickness at all. It started yesterday evening I had a major headache, sometimes they'll go away on there own so I waited it out and nothing.

I took some medicine and got ready for bed, I went to bed with the headache and woke up with it this morning. I wasn't fully hungry so I just grabbed me a small snack and I got sick, I laid down took a nap still had a headache but was able to get a couple hours in. I wake up starting to get hungry so I make chicken noodle soup, 10 mins goes by and I get sick again! I cant keep anything down plus this awful headache.

Could I be dehydrated?

Really debating on going and getting checked out but holding off till my husband gets home.

Also trying to drink gatorade as I heard that can help.
