100.2 fever 4 days PP, is it mastitis?

Brionna
My milk just came in today and I am heavily engorged. I'm not BF due to other issues. I know they said to call the doctor if it gets to 101.4 or higher, is it ok to take ibuprofen?
 
It's been 100.2/100.3. Is that due to my milk coming in or an actual infection? Also having sinus/slight cold issues so idk if it could be that either.
