Low grade temp

So I checked my temp because I feel totally awful 😩. And it was 97.7. My temp is always 98.4 but not today! My Stomach hurts, head hurts nothing is helping my headache go away neither 🙁. Nausea, plus vomiting. AF came the 4th And ended the 7th. Can anybody tell me what the heck is going on. I'm so miserable. Besides with the comments telling me I need to see a doc 🤔. TIA you guys. And please no rude comments!.
