Menstrual Pain

Hello! I figured this is a safe place to discuss my issues. Recently, I’ve been having cramping-like pain when standing or walking. Every day for a little over a week I’ve been nauseous and in pain for a majority of my work day and it’s beginning to worry me. I haven’t had a period in about 6 months and it was only about 3 days long due to having the implant. Prior to this my periods were 10 days long and extremely harsh. Sex is painful recently as well. I’m prone to uterine polyps and wasn’t sure if that could have something to do with this. I have an appointment scheduled in a week, but I’m looking to see if I should be worried.
