Only way to know is to get a test that actually is accurate. Most tests are not terribly accurate, so repeated testing is usually necessary. Your symptoms certainly don't sound like covid, as your highest temperature at what you call "feverish" is still low. But Covid affects different people very differently, some get very few symptoms, some get intense ones, and some take a long time to get the worst of it. But you did what sounds like a very high-risk activity, so if testing is readily available in your area to anyone -- your current symptoms won't allow it even now in many jurisdictions -- you'd not only find out but you'd add to the data base. Of course it is up to you, and again, if you do have it you have a very mild case so far. Peace.
