What do i do if i think i have Covid 19 & pregnant

So i think i have covid 19. And im 28 weeks pregnant. The reason why is because been going out but Not around huge crowds either . Just in the car . I see my baby daddy alot at his house and I always tell him if hes around sick people and he says no. his parents are clean and try to be safe not going anywhere either. .... im not close to them at all i just stay in my baby dads room. Also i went to the mall couple days ago but wasnt there for more than 10-15 mins.. and not around people i tried to self distance. Idk i just haven’t been feeling well .. recently like my body is tired of going to my babys dads house . I need to stay my ass home from now on !! I will not be going over there anymore. Or anywhere else. Its just soooo hard u cant go anywhere when u gotta get food still & u gotta go to the doctors & u gotta go get medication 😰🙏😭... i know its probably all in my head but im feeling weird.. and scared too for my babys life. Im carrying a human being for god sakes. should i be okay? Or should i get tested ? :(

My symptoms are out of breath, tiredness, alittle nausea, no fever, weak.... basically in my chest is all like i cant breathe good.
