Yeah you'll no alright! The pressure you feel is quite intense with all the weight down there lol mine dropped at about 34wks but feels like shes nesttled in there even more this week (36wks)
I could feel it in my pelvis hips and butt along with my upper thighs. My daughter dropped last week at 31weeks. I could tell because of the amount of pressure i felt than had it confirmed at the doc during a pelvic exam.
You'll be able to tell. When someone says it they are referring to how the baby was sitting higher and now is sitting lower. You can tell by looking in the mirror normally. My son dropped at around 8 months, and my daughter never did. Its normally, depending on how much your showing, pretty obvious when it happens.
