Are light periods a sign of poor fertility? last 3days. my ob said uterus looks fine on u/s but i've been struggling to get pregnant for last 8mo.

Light periods ok: The light periods are not associated with decreased fertility. If you are 32 and you have not conceived yet, i would recommend trying to see when you ovulated with OPK and if not, then beginning the workup with your gynecologist to check a sperm count and see if your tubes are patent. Since you've been pregnant in past, i would make sure there are no risk for recurrent miscarriage also.
