Uterus

So hello! I've never been on here before!! I just have a concern id like to share and see if someone can help me:) I'm going to the gyno tomorrow and I have some issues with my uterus. I feel like it's tilted. Every time I put in a tampon it goes straight to the left. Not straight up. And my periods are awful, they are heavy everyday for 6-7 days. I cramp everyday for 6-7. I'm getting birth control tomorrow while at the doctor. Any idea why my uterus may be tilted or does anyone know anything about a tilted uterus? I'm so nervous to go tomorrow!!! 😩
