6 months pp with normal labs but still crashing every afternoon

everything’s technically fine. TSH normal, estrogen rebounding, CBC normal, ferritin’s being handled. but i’m tanking by 2pm like clockwork, cycle’s all erratic, bedtime rage is real. i’m EBF still so prolactin’s obviously in the mix but here’s what i actually want to know: is postpartum hormone recovery just slower for some people even when the bloodwork looks fine? like is there a second-tier test your OB should be running when you feel this foggy but all the basic panels say ‘you’re recovered’. ngl because honestly i don’t know if this is just normal six-month-pp exhaustion or if there’s something that could actually be fixed here. idk if i’m asking for too much
