Heads up i will be seeing a doctor on monday. Idk if im dehydrated or what.

My period was two weeks late,when it finally showed up i had the worst cramps since i was a teen. Then on my last day of my period i got what i thought was the stomach flu vomitting upper cramps diahrrea *tmi* that was 2days ago. Then i got a headache took tyelenol went to bed. Next day i was sorta fine till i got a headache. Now today i just threw up after being naseaus for 10mins amd i had a headache earlier. My anxiety is like omg you have brain cancer. Then my sensible side is like relax its not brain cancer if you still feel sick or gets headaches on the weekend go to the doctors 🤷‍♀️🤦‍♀️ fml
