Diarrhea before labor?

This may be gross and a little overboard, but my husband and I went out to eat. We were at a restaurant only 15 minutes away from our house. We got on our street and I told him he better RUSH the rest of the way.. I walked in and had EXPLOSIVE diarrhea (I know tmi I'm sorry!!). Did anyone else have this before they went into labor? I'm 40+3.
