Covid test for toddler

Hopefully this is the right group. If not please let me know.

Anyone have experience with their toddler being tested for covid? My 18 month old is getting tested tomorrow and I am so worried for her. Not only because I don't want her to have covid, but the poor kid has been through the ringer since Saturday and now I have to watch her suffer and get this test done. Is there anything I can do to make her more comfortable? anything to ease the pain or discomfort after?
