Poop!

I've got a question. Is it possible to poop but be constipated? I've got a pain in my lower abdomen like pressure when I bend over, which is normal for constipation. BUT I've been pooping 3-4 times a day. It's a low volume soft stool each time. I've been having this cramping since Monday night. It could be constipation even though I'm "going", right?
