Chemo

Hello, new here to this site. Loads of good information. I wish I had found this earlier. Just wanting some opinions. My doctor gave me a choice of AC-T x4 and TC x 6. Her recommendations was the TC. I am stage 2a 1.5 cm tumor triple neg. with 1 positive node. I had a lumpectomy. I chose the TC because of her recommendation(she has a great background in breast cancer treatment) but I see most triple negs have some regime with the A in it (anthrocyclin sp?). Did I make the wrong choice when I chose TC over AC-T? Feeling really nervous now. I have had 2 PET/CT scans, one before chemo and one after and all clear and a MRI before chemo and was clear. I am about 2 months out from chemo and going through radiation and am having hip and back pain. Just wondering if there are others with my similar dx that had TC? Feeling very nervous.
