Luna: IMHA for 2 weeks not on blood thinners?

Is there a reason my dog has not been prescribed blood thinners? She was diagnosed with IMHA last Sunday October 16th but was sick for about 3-4 days before that and the vet did not know what was wrong with her. I brought her to an emergency clinic that initially diagnosed her with IMHA, where she got a blood transfusion and the typical treatment for IMHA. After reading the material the doctor gave me about IMHA I asked her about the risk of blood clots and if Luna should be put on aspirin. The doctor said no. The next morning I brought her to a different emergency animal hospital that was open 24/7. she stayed there for three days and did not respond to medicine, I asked if she should be on aspirin because of blood clots and they said no again. They told me she was most likely not going to make it. I brought her home and she has made a significant rebound her PCV went from 20 to 29 percent when last checked on Saturday. Now I’m terrified a blood clot will sneak up on her and take her from me after everything. This vet has been fantastic and is the reason she is still alive so I can’t imagine they wouldn’t be giving her a blood thinner when its one of the easier and more affordable medicines. I called the vet today, October 25th, to clarify but I have to wait until tomorrow, October 26th. Could she be out of the Blood Clot danger zone? Or one of her other medicines is acting as a blood thinner? She is currently on Prednisone, Atopica, an antibiotic for colitis and Cerenia for Nausea. I have had a total of three different vets tell me she shouldn’t be on aspirin or a blood thinner. I’m generally anxiety ridden right now but I also had a Blood Clot and PE myself this past summer…. I’m 23 and healthy so I guess I have some baggage after personally being misdiagnosed and mistreated for that. Any help or advice would be greatly appreciated!
