Funneling cervix?

Just came back from my dr's and he said my cervix is starting to funnel a little at the top. Said my cervix is still long but still wants me to go on disability starting today. I'm only 24 weeks. I'm so scared!! I have another appt on Wednesday with the perinatologist to get their opinion as well. Any ladies go through something similar?
