Flu or??

So I started my period on Monday. A week early, it lasted two and a half days and then stopped for a day then I bled Friday (spotted) for 2 hours then it completely stopped. Then today I woke up today and didn't feel good my stomach won't stop grumbling and I was so queesy I got sick this morning. I haven't been able to eat all day because my stomach is so grumbly. I have a headache and my temp is pretty much normal just up 1.5 but I feel like I'm sick. All drowsy and tired. 
​I don't have any cough or throat problems, or any other symptoms. so I'm a little confused. Is it the flu??
