Baby aspirin?

So let's talk baby aspirin, I began taking it as soon as I got pregnant because of previous losses, then the doctor was like "oh 3 miscarriages and then we will try that stop taking it" then two weeks later I miscarry. I totally regret not following my gut and continuing the regimen. 
Now next time should I just do it and not tell them? From what ive read the possible benefits far out weigh the risks, not only if you have a clotting issue you might not know about but also I would think it would help blood flow to the uterus in fairly sedentary girls like myself. Thoughts? I in no way think I know more than the midwife, but i just feel the 3 miscarriages rule is cruel.
