Rock hard belly for hours straight, sharp pain in vaginal area, and contractions

Jessica

I’m 36w 5d. I went to the hospital 2 weeks ago with contractions every 7/8 minutes. They said I had prodromal labor. Today, all day, I’ve had a rock hard belly, it hasn’t stopped at all, sharp/crampy pain in my vaginal area, and contractions randomly. Along with that, I’m nauseous and I’m having severe lower back pain. Is this active labor? Anyone going through this? It is definitely not Braxton hicks. I have had those since 16w.
