Woke up in pain

Last night I woke up to extreme pelvic, right hip, and back pain. I laid in bed clinching my pelvis. I went to the bathroom and that seemed to work. Now that it's morning I'm still having these pains. Their not as bad but it hurts and I'm not sure if I need to visit the ER. When I miscarried in October 2018 I don't remember these pains. I mainly just bled. When I had my first son in Aug 2019, I don't remember these types of pains either. Has anyone else experienced this or what should I do?
