Active labor or no??

So In the last 24 hrs I’ve gone from completely closed to 3cm dilated and 80% effaced with heavy but irregular contractions. I had my bloody show this morning and am being monitored at the hospital. We live over an hour from the hospital and are terrified for them to send us home if things slow back down since I haven’t felt all this change at all when it’s been happening! Anyone had similar experiences and did you end up progressing soon or did you stay stuck for weeks? TIA!!
