Lab data: These show that you have a slightly low WBC count and are anemic with varying sized rbcs. Without the remainder of the physical exam findings and your full medical records and being able to see you it is impossible to say much more. Medicine is not practiced with labs alone, they are simply an adjunct to good clinical care. See your doctor and feel better.

Anemia: You likely have a viral infection and associated anemia due to the recent menstruation and plaquenil, (hydroxychloroquine) as well as the acute infection. Follow urgent care recommendations but follow up with your regular doctor early next week for a thorough evaluation.
