the Chemo thing part2

I had to take a fourth chemo course, and was told that the regimen needed to be changed to the VE combo (as opposed to EP therapy), which would have caused severe platelet count reduction. However, I was told βHCG was at 1.5 on the start day, so we were back to EP.
anyway, βHCG levels (in my blood) have nomalised to 0.5 now, which was the main objective of the chemotherapy.
