Pelvic pressure along more discharge

I’m 30-31 weeks almost and this is my third pregnancy. She’s head down and All of the sudden I feel nonstop pelvic pressure / kind of like mild lightning crotch pain with pressure but more consistently. Plus, increased discharged along. I really don’t remember this happening this early in the other two. Is this normal? Baby just engaging on my pelvis? Or should I be concerned and tell my midwife? Totally forgot and don’t want to be alarming.
