Higher birth control

Re

So I had to go to the hospital on Tuesday morning (1/22) and i started my period the evening of the 21st... My cramps have been extreamly bad. I have been told that with me still getting severe cramps and a period while on birthcotrol i will possibly have to be on a stronger birth control method. My period has lasted 1 and a half to maybe 2 whole days... I use the diva cup and my perod blood is usually a lighter brown with a few small clots but this has been a very dark brown and very very little.. Has anyone else been through this? Im really nervous and have an appointment with ny ob on Tuesday (1/29) but my mind and my anxiety is making me think the worst 😣😣 any advice please!!
