Missed treatment

I'm just about to complete my 4th cycle of chemo. Ive been really struggling with very low platelets, and other low blood results which has resulted in me missing a few treatments. This has made me really anxious and made me question if the chemo will be as effective. Im also really nervous as I move to EC treatment next week for 4 cycles, very worried to how my body, and especially blood levels will cope. Anyone else been through a similar situation? Many thanks.
