A common question for providers following an early pregnancy loss is how long to wait before trying to conceive again.

The authors of this study (Obstet Gynecol, 2016) analyzed data from a well designed RCT that looked at the effects of preconception-initiated aspirin in women with prior losses (Lancet, 2014). In this present study the authors were able to compare 765 couples who attempted conception within 3 months to 233 couples who waited longer. The authors did adjust for aspirin therapy, although results did not show any significant effect.
