102.3 degrees fever

Ichigo • I have one daughter. I'm also pregnant with my second. Unmarried.
Not controversial I know I don't care. I've googled it and come up with different advice.
If I have a 102.3 fever, I should call the doctor right? Or should I wait a day or so to call? I've only had it today. Also the shivers a horrible headache, I feel too weak to get out of my bed, and no appetite. Plus an 11 day old.
And no one help me with said 11 day old because her fucking father doesn't have a fucking phone and disappears all the God damn time so I can't even text his fucking family because they're always asking
Me where he is!!!
FURY.........
