Oral thrush?

Sherlyn

Little back story I had bad oral hygiene and my dentist gave me a full clean and some of my gums were swollen as well they gave me a mouth wash called chlorhexidine, I’ve been using it daily since September 7 but about 2 days ago I saw these small red bumps on the back of my tongue I also noticed my tongue having this white stuff on it I brushed my teeth and scrapped at it as well I don’t usually do that to my tongue tho. Would that mean I do have oral thrush? I can’t afford to go to a doctor rn which is why I’m asking on here if any are doctors and know about this. Any type of help will be helpful or tips for at home remedies that can help my oral thrush go away. Thank you.
