Is this possibly the start?

I got sudden nausea, and dizziness. I've had diarrhea today. With my first I was induced with a cervix ripener. I didn't get any pitocin but I felt extremely nauseous right before active labor actually hit. Could this possibly be the beginning of labor? Babies dropped and my vagina is on fire and my butt bone has had a lot of pressure. I know I know I'm probably just being hopeful lol I'm over being pregnant
