Ftm help please

The other day I went to my prenatal appointment and the doctor checked my cervix. She said I was dilated 3 cm. She also said from the pressure of the cervical check that I could have some bleeding. This all happened 2 days ago. Although I didn’t have any bleeding, about an hour ago I woke up from a dead sleep having to go to the bathroom. When I wiped there was a ton of mucus that was really slightly tinged blood. Wasn’t very much blood. I do feel baby very active right now on the right side where his feet are. Since I tested positive for GBS, I’m not exactly sure when I go to the hospital. I know I have to be there 4 hours before my son is born but like when exactly should I go? I know none of what I shared here is a sign of labor really but I’m nervous I won’t make it to the hospital in time. This is my first baby.
