Happy to hear its gotten better!
If you're only planning on one blood work, make it week 6-7. That way test levels should have peaked and so should estrogen if AI is to weak/high.
Just make sure to get female hormone panel as well, so you know estrogen values and can tweak AI if need be from there.
Would also be good to know hematocrit levels at that point since it was at 44-45% last check up.
