Pelvic Pressure, upset tummy - 37 + 2

Hi ladies, just wondering if anyone else is experiencing or has experienced this?
I'm 37 + 2 and have SO much pelvic pressure! Midwife says baby's head is engaged. There is that much pressure down there i literally feels like i'm going to pee myself all day!! Feels like i might wee when baby kicks down low!
Also had a really upset stomach all day today which i've heard can be a sign of labour? Been to the loo 4 times (sorry if TMI) and have a lot of on and off sharp shooting pains in my vag! 
No contractions though!?
Has anyone else experienced this? I'm a first time mum so would appreciate any advice 😊
