Yesterday i woke up with dull headache, was nauseus and vomited. i am 100% not pregnant. can it b sth dangerous? i had similar situations in life

Pattern: If this pattern continues then I would see an MD to make sure there is not a buildup of pressure during the night when you are flat causing the headache in the a.m with vomiting.

If it has been: happening frequently then it needs to be worked up. more than likely you could be having migraine headaches. it is common to have headache along with nausea and vomiting with migraines. it is very common in young women
