Am I going into labor?

Okay, I'm a FTM and I believe I have begun labor. I'm 37 and 1 day, and I have been having contractions since Monday night. I went to the hospital and was sent home 1cm dilated. I have been having contractions all week, but tonight my contractions are a lot more intense. I'm feeling a strong tightening in my belly and sharp pains and cramping above my vagina, along with "crotch lightning". They seem to be 5 mins apart lasting 30 seconds.
Someone please answer me rather than just viewing and leaving me in the dark . πŸ˜’πŸ˜”
