The evil period

I started my period Wednesday of last week (May 22nd) and it was horrible. Between the pain, bleeding, and clots I didn’t want to move. Heck I couldn’t move without a clot passing. As of today I’m on day 7 (May 27). This is my second cycle off any type of birth control and I knew it wasn’t gonna be pretty but I feel like it’s kinda enough. I start my new birth control on the first. And I don’t know if I should call my dr and ask to start earlier or what. Advice would be greatly appreciated.
