Pooping a ton?

Anybody else having similar symptoms? I'm 36 and 5 just had my 37 week apt so I talked to my ob about my new bm habits and she said it sometimes your body getting ready for labor. I've been having 3-4 bm a day and I seriously always feel like I have to have one even when there is nothing there. During my exam she said I'm not dilated but the head is sitting super low. Anybody else feel like they are spending too much time in the bathroom?! Maybe I'm the lone weird one!
