Should I call my doctor?(OBGYN)

I’m not sure what to do on this, sometimes my periods are 4 days long and the first two days are horribly awful.. and today mine started and I have literally massive pain in my back and all over my stomach. I want to cry. Usually I’m able to handle the pain, but I’ve taken Advil and Motrin to help it, it only does it for temporary. My primary doctor told me that I am slightly anemic and I have to take iron supplements. Currently this is unbearable. I haven’t been on birth control nor sexually active since October. I’m not sure what to do at this point..

any advice is appreciated. :(

* I want to try and not see urgent care or the ER for this as my insurance doesn’t cover much on those visits and I don’t want to take up space for people who are actually sick and need to see a doctor.*

*Update: I saw my OB today and she was a bit concerned, I’ve been placed on the pill to not have as painful periods, and also a iron supplement.*
