Anyone go through this?

Last night around 9 it felt like I had a small leak but I laid for awhile got up and my underwear didn’t get soaked or anything so I figured it wasn’t a leak.. then at 1am I woke up to extremely paint contractions. They were almost getting really bad then I had diarrhea but around 4am they slowed down and I was able to sleep.. this is my second child but this didn’t happen before. Has that happened to anyone and you gone into labor shortly after?
