I lost my mucus plug last night and now i have a lot of yellow discharge.. normal? im 38.5

Probably ok: It is very normal to have an increase in vaginal discharge that is yellowish or snot like as your body is getting ready to go into labor. There is not actually a plug of mucus that holds the cervix closed. Rather, the cervix produces mucus as it starts softening. Call your doctor if discharge is like water, or you have strong painful contractions regularly every 5 min or less for an hour
