Signs of labor?

Whitney

So I’m 36 weeks and a few nights ago I woke up to intense contractions they were 5-6 minutes apart lasting a minute. I got a bath and ate a snack and they went away so I went back to bed. The past 2 days I’ve woken up at midnight feeling extremely nauseous which leaves me to be exhausted ALL day. I drink 107 ounces of water a day so I know it’s not dehydration. This isn’t my first child & she’s already dropped. (I’ll post a pic below). This pregnancy is completely different than my first. How were you feeling the a few days before you went into labor?
