Early labour or is this normal

Hi I’m 32 weeks with my first and he’s been head down for a few weeks now but past few days i feel like baby dropped down a lot to my pelvis, going toilet every 20 mins, experiencing firm amount of braxton hicks but they are irregular, a lot of lighting pain in my crotch and since last week I’ve been loosing bits of mucus plug but without any blood. Is this all normal for 32 weeks or do I need to call my midwife?
