So glad you are doing okay. It is good that you called your doctor....I guess they see these "Complications" all the time..and know when to send you to ER.....
I wonder why bleeding would give you shortness of breath????
My son was very nauseous and had no appetite at all and it was because he had been swallowing blood and not knowing it. But no shortness of breath..
At least you know what to watch for and are keeping an eye on it. It is really scary though as we are not doctors and do not know sometimes what is okay and what isn't! I would still go to ER if it does not seem to be getting better or if you are really concerned. Not that I would want you to have a second surgery!!! But you don't want to continue bleeding either and also sometimes a doctors reassurance helps!
It sounds like you have it under control though and know what to watch for. You are almost through the recovery!!

Just remember to still take it easy..nothing strenuous!!
Hang in there!
