Let's talk bowel movements

Hi ladies, FTM here. Currently 34 weeks+2 days. For those of you that have given birth before, did you have diarrhea leading up to the day of delivery and/or the start of your labor? It's been nonstop for me today- no changes in diet either. Every time I eat or drink something, I'm running to the bathroom. That's coupled with what I feel like are period cramping although I'm sure it's Braxton hicks contractions, as I've gotten them before. I prefer to call it cramping. I just want to get a feel on whether or not the whole diarrhea thing before giving birth is accurate. I've had the uncontrollable urge to nest for the past few days and boom now this has hit me all day.
