Common cold treatment during pregnancy?

Manal • Soon to be a mommy of 3 under 3
Hey there
​I'm very sick :-( I keep sneezing,coughing & I have a sore throat & just achy all over 
​When I sneeze or cough my abdominal muscles & my uterus area hurt so bad :-(
​I feel like I'm going to sneeze the baby out 
​How I can treat this? 
​I seen a doctor yesterday & she said do not take any meds during the first 3 months! 
​I usually don't since most of meds aren't vegan,but I'm so sick now & I'm worried about my baby that I'm ready to take meds! I don't want anything to happen to my baby I think all this coughing is going to hurt it :-( 
​What can I do to cute this?
