Pooping TOO much?! TMI

Okay I'm going anonymous because this is embarrassing. I'm 26 weeks and the past two days I have been pooping SO MUCH. It's diarrhea because it's always normal shape and stuff, but when I have to go it's like I have to go NOW or I start cramping and it hurts. My bowel movements have been normal throughout pregnancy until now. Is this super normal? Like I just got done and it feels like I have to go again?!
