It is quite common for both OBGYN and Fertility doctors to encourage their patients who have had multiple miscarriages take baby aspirin in order to reduce the risk of future pregnancy losses. The problem with this is that these recommendations were never really backed up by research to see if aspirin is really effective in preventing miscarriages. In order to determine if this common practice was effective, the NIH conducted a large trial to see if taking daily baby aspirin would reduce the risk of subsequent miscarriage in women with 1 or 2 prior miscarriages. Unfortunately, as reported in the journal Lancet, baby aspirin did not help and these women were no more likely to experience another pregnancy loss than those who took a placebo. The one bright spot in this study: women who took had a single loss early in pregnancy within the last year and took baby aspirin were more likely to actually become pregnant.
