Will I go into preterm labor?

Hey everyone! So I went for my check up today. I’ve been having cramping for weeks now and bad round legiments pain. Last week I also had an appointment and was check and she said my cervix was good. Now a different doctor in the office checked me today and said it’s closed and the length feels fine but it’s a little soft. She said she’s not worried about it and to check my cervix length in my US in 2 weeks. It made me really nervous even though she said it’s okay. Has anyone else experienced this? I’m 25 weeks 4 days.
