Feeling scared

Hi all I had cin iii in 2008 smears been grand since. Due to this I have had my entire cervix removed so periods have been just spotting since then. Last month I had my first really heavy period lasting 8 days and yesterday another heavy one. I woke up thismorning and I have a really foul fishy smell comming from my period never experienced it before . The pain in my pelvic area is unbearable . Not sure if related but I've had a persistent cough for 3 weeks (not covid was tested) . Anyone had that foul smell from a period? Thank you
