engaged?

[Kittytat]

hi there, i was just wondering how to know when the baby engages! i asked the doc and he said i would feel discomfort in my inner upper thighs! is this true? i seem to be going to the toilet alot more the past 2 weeks like every hour to hour and a half at night and i find it hard to walk too much! i am also getting alot of lower back pain! and if i move around too much the braxton hicks just start going off! im only 35 weeks pregnant!
