ANswer to question 1 is no but YES for 2 and 3 as my work is kind i have to meet daily over 100 peoples (was involve in some social work ) .so far no breathing problem but light fever,always feel tiredness ,weakness and pain (mostly headache but sometime in body too ) thats y worried esp bcoz of my parents ,was in self quarantined .Today Allah ka karam feeling much better but if that problem persist better do covid test for the safety of other members of family
best is just to get test if possible. Incubation period is at least 10 days or even more. You may feel better but this can change rapidly. Be safe in sha Allah
