31 weeks

I’ve been in l&d twice this past week with contractions but no change to my cervix. I’m still having contractions but they aren’t as consistent and aren’t very strong. I’m also having period like cramps along with a back ache and diarrhea though. My dr moved my appt up with him to this Wednesday instead of 2 weeks out. Has anyone dealt with anything like this and what will he do most likely? I feel like I’m having all the symptoms of labor just not dilating😩
