Severe cough

Annelise • Mom of 5
I've had a bad cough since the beginning of my 6weeks. Doctors are telling me it's fine an I just need to red n drink lots of fluid. I'm hoping it doesn't hurt the baby as it is really hurting me. Losing my voice. And to top it off morning sickness everyday for the past 3days. The only good thing is no more 100temp. So should I be okay or be worried??
