12 days no AF have had pelvic pain and back pain

Good morning beautiful ladies. I know I posted previously but now I am 12 days no AF and have back pain, like I can’t stand for too long or it’ll start hurting like hell. Pelvic pain comes on and off still but I can’t seem to get any rest 😔. I try everything to sleep but I constantly keep waking up every other hour or so🤦🏽‍♀️.
