Anyone else 34-35 weeks experiencing this or delivered early and had this?

Britinii • Boy mom. 💙💙💙 Our 3rd boy due Nov.

Been having pelvic pressure all day. I feel like I have to pee non stop even after I pee. Been having like lightening pains shooting up my butt. Lost some of my mucus plug but no blood so I assume it will regenerate and is normal. I have had lower back pain for the last two weeks but a heating pad is helping. Just wondering if anyone else is experiencing this or has went into labor early and experienced any of this?
