My recent blood test showed , esr and rdw levels slightly high, and hematocrit level decreased slightly. should i be worried?

Maybe: Not everyone will agree but as a pathologist, I do not worry about elevated sed rates especially if mild and you otherwise feel well. A slightly high RDW and mild anemia in a young woman suggests mild iron deficiency and your physician will follow up as appropriate. We'd get supporting labs, and blood loss from some other source than your monthly cycle would need to be ruled out.

Lab data: Difficult to comment on lab results without clinical correlation, but you are slightly anemic and if this is iron deficient anemia it may be because of bleeding during your period and may require iron supplementation. The increased ESR and CRP are probably of no consequence. Get an answer to why your hemoglobin is low. Good luck.
