miserable

I'm 32 weeks and I've had a terrible sinus infection since Wednesday (it's now Sunday) I had to go on a long 6 hr car ride Friday and Saturday and I was experiencing Braxton hicks the whole time. Today I haven't done much but lay around. I feel horrible. My head is still killing me I'm crampyand have had horrible Charlie horses in both legs and I'm coughing really bad. My back hurts and just flat out uncomfortable. Any advice ?
