I too have been having this. Pelvic pain is worse at night when I’ve been laying down for hours as well as aches in my arms and legs! Wakes me up from sleep and keeps me up for a few hours. It’s the worst! I also have it when I’m not on my period, but i do feel it slowly start to build over a few nights until the pain is unbearable! Not sure if it common/normal, but I have it too. Makes me exhausted the next day!
