Major headaches & fatigue

Thelma
Feeling exhausted & have had headaches/migraines for the past few days. I'm 5 wks pregnant.. Pain has been so bad I've taken 1 Tylenol 500mg per day... My first doctor's visit is not until 3/24. Any suggestions or recommendation ? I've also used this for the pain: I heat it up & wrap it around my eyes....
