Common or not?

I'm 25 weeks 3 days and my feeling of needing to pee is ridiculous. I'll pee and rifht when i stand up from peeing, i immediately feel like I need to pee again even though I know I don't. I know peeing often is common but is that feeling normal? Also is it normal for the vagina to start feeling more swollen and my cervix to feel lower? I'm freaking out a bit because it makes me feel like baby is lower than he normally is. Is it just because he is getting bigger and I should get used to this feeling? Should I call my midwife and express my concern? Please help 😰
