Hormones 6 months postpartum

I'm 6 months postpartum and the past month or so, my acne has EXPLODED. Like never been this bad 😅 I've also been really fatigued and tired beyond the usual tiredness and had severe abdominal pain when I have dairy (which is very unusual). I'm going to the doctor on Monday to see if something is out of whack in my hormones, but I wanted to see if anyone else has had a crazy time with hormones postpartum, even 6 months after birth. This is my fifth child and I am still exclusively breastfeeding, so no menstrual cycle yet. Thanks in advance ❤️
