What's wrong with me, am I pregnant?

I haven't had my period since May meaning I missed one completely and was expecting early this week

I took a pregnancy test yesterday afternoon which came back negative.

I've also been sick for the last two weeks, it's started with a stuffy nose and green mucus

A week ago I went on a trip to newzealand and I got severe earaches and began coughing up mucus.

When I returned I had a stuffy nose and bright yellow mucus when I blowed it.

The last few day I was coughing like crazy and last night I coughed so hard I vomited. Then today I have vomiting anytime I eat something.

I've also had very limited bladder control recently.

Sorry for all the probably irrelevant information I just want an answer.

Oh also I have been sexually active continually for the last 8 months I am on the pill.
