13 weeks and 3 days (help)

is anyone else throwing up constantly and can’t keep anything down? i’ve been doing well lately until today. i woke up with a pounding headache, and threw up immediately, it was so bad i had to force myself back to sleep. then i woke up and was feeling decent, decided to doordash some food. all i was able to get down was my salad before puking 4 more times. i’m super dizzy, and so nauseous. should i just try to eat again or should i take another nap? i don’t know. is it even normal to be sick in the 2nd trimester? like this is much worse than my entire first trimester. i’m just clueless. i need help. if anyone has any advice or is going through the same thing, please let me know. this is my first pregnancy and it feel so bad right now.
