Baby aspirin a day? Experiences/thoughts?

After having two miscarriages I asked my doctor about taking baby aspirin next time I’m pregnant. She said it may or may not help but if I wanted to try it that I could and she said I could even start taking it now (we won’t be trying again for a couple months).

What is everyone’s experience with baby aspirin to prevent miscarriages?

Is there any risk to the baby? Would something bad happen if I took it for a long time and then just stopped? I always feel weird taking stuff for long periods of time, but she didn’t seem concerned about the idea of me starting the aspirin now and continuing throughout my next pregnancy.

Thank you!
