33 weeks pregnant and PRESSURE like you wouldn't believe...?

Anyone else out there between 32 - 34 weeks and having a lot of pressure? I walk around all day feeling like I have to have a bowel movement, but I know for a fact I don't. I think it's just the baby lying really, REALLY low. I'm also having a lot of pressure on the front part of my pelvis. Can anyone sympathize with me?! Are there any ways to relieve it? I can't walk around for the next 2 months like this!!
