Aspirin Therapy success stories in Pregnancy?

Hi im about to try for baby no1 after 3 m/c i had lots of tests done the only thing they found was im positive for ANA ( anti nuclear antibodies ) no other immune problems at the minute.. My doctors wants me to take low dose aspirin as this helps with recurrent m/c i would just like o hear from anyone that themselves or anyone they know had to take aspirin through out their pregnancy and how things worked out.. many thanks in advance
