Light period

Partner is 33 I’m 41 turning 42 in January. Doc said I’m ovulating but my period been super super light compared to before my d&c last November. One light day then maybe medium then couple more days of light light.

Been ttc-Ing since then with no luck. I read somewhere light period isn’t good for ttc cuz the lining isn’t thick enough for the egg to implant. My ob who did the d&c kept saying it has nothing to do with it but I’m skeptical. Definitely a before and after difference since the d&c. Is she right or I should find a new ob. Thanks. I hate using google doctor but .........
