HELP!

Last night I was close to going to the ER. I couldn't breathe, had shortness of breath, and I have a bad wheezing problem.. and I felt like I was having an allergic reaction. What's worse is that I'm pregnant and I'm afraid to take any medicine to treat it. My next doctor appointment is on the 30th.. I figured since its only a couple more days I can hold it off long enough.. Everyone is telling me to just rush to the ER and get checked before anything else happens. What to do? I'm afraid to go alone. Everyone is either working or busy..
