Consistent contractions for 2 hours and then stop

Kaitlin

So at 2 different times now I have had consistent contractions for 2 hours straight and then they start slowing down and then they stop. Has anyone else experienced this? I take Tylenol drink water and change positions when this happens and nothing helps and my whole stomach gets hard they are about 6 min apart when it happens. Wondering if anyone has experienced this and what ended up happening. It happened 2 weeks apart and I am 34 weeks I was only a cm dilated yesterday so I guess the contractions aren’t dilating me but I’m confused as to why they keep happening when I’m not in labor.
