Those ARE freakishly good results! Congratulations!
I haven't had any blood drawn since 8 weeks either except for my MaterniT21 blood draw. However, I got blood drawn today for my glucose tolerance test (1 hour), and I believe they also test that sample for anemia and other blood-related issues. The tech who was drawing my blood told me, "Celebrate, this is one of the last blood draws you'll have to do!" Assuming I pass the GTT, of course...
