37 degC considered fever? Been having on & off for more than a week. Should i go to kkh?

Hi mummies/mummies to be. I'm at 15 weeks. Last week Monday when i got home from work and resting, i had migranes and my feet start to feel cold. Checked my temp at 37degC and it went on till Friday . Started having again this week. On top of that, feeling weak, breathless and some chest pains. Had a video call with a GP and she said to go hospital straight. But my bro who is an emt said it's probably anxiety. Should i go to kkh? #pleasehelp #firsttimemom
