I have also been in contacted which was for about 2 min with someone who tested positive for covid 19,we both had our masks on and this person was about a meter away from me?

Test/isolate: Have a screening test for COVID 19, self isolate and rest. Monitor your temperature and breathing. Take Tylenol rather Motrin for fever control, stay well hydrated.

Yes, get tested: It is important that exactly people like you get tested, so that we can learn of people with just minor "cold symptoms " or no symptoms like yours may actually have a mild case of Covid19. It also let's you know whether you need to keep a full quarantine. You are absolutely correct that it might be nothing, but the best option is still to get tested!
