Thank you for your reply and calming my nerves. I am actually about to head back to my PCP to do a redraw this afternoon. The last CBC that I had done was back in 2009, and my WBC, RBC, and platelet counts have dropped since then (but that was 9 years ago and it was during my pregnancy).
I am anxious to see what has changed in the last 3 weeks. For now, I think I just need to be patient and stop worrying.
