Bleach inhalation, now what do I do?

My husband bought some Tilex (contains bleach) for our bathroom. I sprayed down the tub, left the room for a bit (the door and window were open, mind you) and came back a little bit later to scrub the tub. I don't think I was in there for more than 15 minutes, but the bleach smell was very strong and my eyes and nose burned while cleaning (I also had a scarf wrapped around my mouth!). After I was done, probably about 10 minutes after I sat down, I felt nauseous, had an instant headache, got very sleepy and felt like I was running a slight fever (had the chills too). The weird thing was that the symptoms came in waves, so I dismissed it. I woke up this morning feeling better (no nausea), but now I have a slight cough and some chest tightness. The chest tightness is similar to bronchitis, when you breathe in and it's slightly wheezy and you have to strain a bit to take a breath. I'm worried that all the bleach may have had a really adverse affect on me. What should I do? Should I wait to see if my symptoms worsen/improve? Has this ever happened to anyone else? I've been googling the side effects of bleach inhalation and people have said that a good amount can result in pneumonia, fluid in the lungs, vomiting, coughing, etc. Any suggestions? Should I see a doctor, just in case?
