Night sweats 7 months postpartum

So I am 7 months post partum and still exclusively breastfeeding. I had night sweats the first few weeks postpartum, but then they stopped. They have now ramped up again in the last couple of weeks. Anyone else having this after several months of breastfeeding?? I did get my period yesterday, so I’m wondering if that’s related. I don’t have any other unusual symptoms, but I did mention it to my doctor to have my thyroid checked!
