Pretty sure baby is engaged now

Holy hell the pressure! This morning the baby dropped really low, and now I can barely walk. I have horrible pressure in my pelvis, hips, and vagina. I feel like the baby is gunna fall out (yeah right like it would be that easy to have a baby lol). This is my third time around, but i don't remember this happening so early in the past (I'm only 29 weeks). Any other seasoned moms out there that have had this happen? I'll admit, I'm a little nervous about it happening so early, as I was at this point in my last pregnancy when I went into premature labor.
