Positive for Covid

I came to the hospital because I was having so much pain from chest going down my whole back and right to my legs and couldn’t walk at all . I’m happy to say that my daughter is healthy and strong but I tested positive for Covid and don’t know how because I don’t go anywhere and if I do I wear double mask and clean my hands . The doctors don’t even know how I got it because I’m always home. But I’m just happy the baby is doing good & she’s not coming out yet
