cervix and dilating and pink eye

Katice💘

so i’m 39 weeks and was told my cervix is open 2cm. but what’s the difference in that and being dilated?

and i got pink eye a week ago and the medicine they gave me was trash so i got more. but i read babies can get it coming out the birth canal. but does that mean i’ll have to have a c section if it’s not clear by next week?
