Sick shoukd i head to the er?

April
I came down with a cold that now has affected my asthma and ive been struggling to take a deep breath because my lung gets this sharp pain. I am 32 weeks pregnant and I can feel baby moving but I'm scared she isn't getting enough oxygen as I feel out of breath and struggling a bit. Should I just go to the er? my appointment for my dr isnt till the 6th so I'm not sure what to do.
