29 weeks and feeling the need to push

Elizabeth

So im not sure exactly how to describe this feeling. I dint have it currently because it comes and goes depending on the day.

Anywho, it's like out of no where I'll get a ton of pressure in my lower pelvis through my butt hole, like she's trying to come down and out. It doesn't hurt at all but the pressure is overwhelming and I panic a bit because I feel like I need to push her out.

I'm not constipated, I don't have diarrhea, I don't have to poop and the feeling can last all day or maybe just an hour. Any ideas or advice? And no I haven't gone to the hospital because it goes away, doesn't hurt and there's no discharge. Also, laying down only helps till I stand up again most if the time
