Breathlessness?

I am slated to have the start of round 3 tomorrow (dose dense carbo/taxol)... and I feel like crap. I have no energy and if I climb the stairs from the basement, I am out of breath. I have no temperature and no swelling anywhere.  From another forum, sounds like my blood counts really dropped (they were low last week, but above the cut off, so the final taxol in round 2 was given).  I am hoping that the infusion center posts my counts tonight (they use MyChart) so that I can see.... but could they have me get a platelet infusion? blood infusion in general? How is that done (ie, is it done through the Port)?  so many questions and I am so tired.......

Thannks for any suggestions.
