Pressure while trying to go #2

Taylor
I'm currently 26+2 days, and I'm almost afraid to go to the bathroom. I won't strain myself too hard, I know I'm slightly constipated, but here lately it will feel like a ton of pressure on my pelvic region/vagina when I'm trying to poop. It feels almost like I'm just opening up down there or something! Is this a normal thing? I'm probably going to end up calling my doctor tomorrow anyway, but have any of you experienced this?
