Question about baby dropping? [pubic bone] [bladder]

I am 31 weeks. Is it possible that my baby dropped? This morning I woke up with my baby punching me right above my pubic bone. Ive never felt so low before her. Dh I put my hand there and we could actually feel the baby (possibly her mind). Then I looked in the mirror this morning and you can see them below. Secondly, I pee more often and its much more pain when she puts on my bladder. The reason why Im so worried, because when I asked my sister she said she heard that babies can drop to 4 weeks
