Pelvic pressure and constant urge to poop- baby coming early or normal for 34w?

[myra]

For a few evenings now, I've felt like I had to poop but can't- just have pressure. Then yesterday evening through til this morning I had a lot of pressure in my pelvic area (kept feeling like i do at the start of my period), some sharp twinges in lower abdomen and crotch and kept feeling like I had to poop- but couldn't. This morning I popped 3 times within an hour of getting up and that relieved some of the pressure. I haven't had any more of the twinges and there's less pressure now. Curious if these are signs baby might be getting ready to come early or if it's just all part of the natural process. (My son was born at 29weeks, so all this is new to me at 34 weeks)
