MIA Period

Hello! Maybe there’s some fellow mamas out there that may be able to give me some input. I have an 8 month old baby that stopped breast feeding 4 months ago. I should have gotten my third post partum period 10 days ago. I have insane acne, fatigue and mild cramping off and on for the past week and mood swings. Could things still be a little out of whack or should it be regular by now?
