Pressure in lower abdomen/upper pubic area??

Hi ladies, so I am 21 weeks with number 2 and have been feeling pressure and the baby's movement really low since like 17/18 weeks, especially when I've been standing a lot, and just can't remember if that's normal? Am I just carrying low? I also feel like since I've been pregnant I've had a lot of secretions/pee slip out down there all the time too. It's been like 4.5 years since I've been pregnant so I totally can't remember what's normal. lol. Anyone else have this? This is my rainbow pregnancy so I guess I'm just extra paranoid.
